Update quarkus-native-image-maven to use more up to date practices and updated to Java 21

[miller79]

Summary

The following was changed with the PR:

• Updated maven.compiler to 21
• Updated README.md to use BP_MAVEN_ADDITIONAL_BUILD_ARGUMENTS instead of BP_MAVEN_BUILD_ARGUMENTS. This change allows the default values in the build arguments to be used which includes the following:
  • -Dmaven.test.skip=true --no-transfer-progress package
• Updated README.md to use Java 21
• Updated README.md the BP_NATIVE_IMAGE_BUILT_ARTIFACT to use a wild card for the runner.jar

Use Cases

Changing from BP_MAVEN_BUILD_ARGUMENTS to BP_MAVEN_ADDITIONAL_BUILD_ARGUMENTS allows the defaults given by BP_MAVEN_BUILD_ARGUMENTS to be utilized for free. If these change in the future, they will be automatically added without having to be aware of these changes.
