feat: migrate away from deprecated graal-sdk dependency to use nativeimage

[mpeddada1]

Merge after https://github.com/googleapis/java-shared-config/pull/815 is released and updated in sdk-platform-java.

According to the graal/sdk CHANGELOG, the GraalVM SDK was split into smaller modules and the use of graal-sdk is deprecated. The new maven configuration to customize native image generation is:

<dependency>
  <groupId>org.graalvm.sdk</groupId>
  <artifactId>nativeimage</artifactId>
  <version>${graalvm.version}</version>
</dependency>
