openapi.properties file not taking into account when using kapt from Micronaut 4.4.0

[agartime]

Expected Behavior

Properties defined under openapi.properties are not populated when using kapt from Micronaut 4.4.0.

I expect openapi to generate the definition yaml file in the path specified under micronaut.openapi.target.file, and not in the default path under META-INF/.

api.version and openapi.title properties are broken too.

Actual Behaviour

micronaut.openapi.target.file property is ignored when is set under openapi.propertiesfile and "io.micronaut.openapi:micronaut-openapi" dependency is declared with kapt:

kapt("io.micronaut.openapi:micronaut-openapi")

Full stacktrace can be seen here:

error: Error finalizing type visitor [io.micronaut.openapi.visitor.OpenApiApplicationVisitor@407e6e29]: Invalid relative name: META-INF/swagger/${openapi.title}-${api.version}.yml
  java.lang.IllegalArgumentException: Invalid relative name: META-INF/swagger/${openapi.title}-${api.version}.yml
        at jdk.compiler/com.sun.tools.javac.file.JavacFileManager.getFileForOutput(JavacFileManager.java:898)

The problem doesn't happen when ksp is used for "io.micronaut.openapi:micronaut-openapi" dependency, or when using micronaut < 4.4.0.
