[FEATURE] BOM: add Spring Boot modules

[me0106]

Now, if you want to reference multiple langchain4j modules, you always need to define multiple 'artifacts'.

like this:

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-core</artifactId>
                <version>0.23.0</version>
            </dependency>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-open-ai</artifactId>
                <version>0.23.0</version>
            </dependency>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-azure-open-ai</artifactId>
                <version>0.23.0</version>
            </dependency>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-elasticsearch</artifactId>
                <version>0.23.0</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

It would be great if a single BOM could be provided. Just like jackson-bom

    <dependencyManagement>
        <dependencies>
              <dependency>
                  <groupId>com.fasterxml.jackson</groupId>
                  <artifactId>jackson-bom</artifactId>
                  <version>${jackson-bom.version}</version>
                  <type>pom</type>
                  <scope>import</scope>
              </dependency>
        </dependencies>
    </dependencyManagement>

Sounds great. I think it's a good way to manage artifacts.

@me0106 could you please clarify? Do you expect that declaring a single dependency will automatically import all available langchain4j modules? Or that it will only import right versions and you will still need to explicitly define which modules you want? Thanks

@langchain4j This PR is actually what I need, https://github.com/langchain4j/langchain4j/pull/227 I usually define all the dependencies required for the entire project in a parent to avoid various version definitions in the submodules, including variable references in the format of ${xxx.version}. If there is no unified BOM provided, I have to define all versions of langchain4j in the parent pom,

--------//parent pom
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-core</artifactId>
                <version>0.23.0</version>
            </dependency>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-open-ai</artifactId>
                <version>0.23.0</version>
            </dependency>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-azure-open-ai</artifactId>
                <version>0.23.0</version>
            </dependency>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-elasticsearch</artifactId>
                <version>0.23.0</version>
            </dependency>
             <dependency>
                   <groupId>dev.langchain4j</groupId>
                   <artifactId>langchain4j-pinecone</artifactId>
                   <version>0.23.0</version>
        </dependency>
        </dependencies>
    </dependencyManagement>
 ----- //sub module
 <dependencies>
       <dependency>
            <groupId>dev.langchain4j</groupId>
            <artifactId>langchain4j-elasticsearch</artifactId>
      </dependency>
       <dependency>
                   <groupId>dev.langchain4j</groupId>
                   <artifactId>langchain4j-pinecone</artifactId>
        </dependency>
 </dependencies>

If there is a simple BOM that can be referenced, I only need to define one <dependency/>:

//parent
  <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>dev.langchain4j</groupId>
                <artifactId>langchain4j-all</artifactId>
                <version>0.23.0</version>
                <type>pom</type>
            </dependency>
       </dependencies>
  </dependencyManagement>
// sub module
 <dependencies>
       <dependency>
            <groupId>dev.langchain4j</groupId>
            <artifactId>langchain4j-elasticsearch</artifactId>
      </dependency>
       <dependency>
                   <groupId>dev.langchain4j</groupId>
                   <artifactId>langchain4j-pinecone</artifactId>
        </dependency>
 </dependencies>

And if a new module appears in langchain4j, I don't have to define them one by one, I only need to upgrade the version and then directly use it in the submodules.

Having a unified BOM can simplify the definition of the parent.

[langchain4j]

is available since 0.24.0

[nikbobo]

is available since 0.24.0

I hope you can provide a BOM that includes the Spring Plugin and Spring Boot Starter.
