chore: settings.xml from actions/setup-java (#182)

Refactored the Maven setup process to avoid redundant creation of
`settings.xml`. This uses the configuration options provided directly
within the `setup-java` action. This change reduces duplication and
simplifies the workflow for both GitHub Packages and Maven Central
publishing.
