Migrate CD to maven central

[TingDaoK]

Issue #, if available:

• migrate to maven central. since Publishing via OSSRH will be sunset on June 30th, 2025

Description of changes:
Details about the new Maven Central API can be found:

1. Maven Plugin : https://central.sonatype.org/publish/publish-portal-maven/, which we used to publish snapshot here
2. Publisher API: https://central.sonatype.org/publish/publish-portal-api/, which we used to publish our classified JARs.
3. OSSRH - gradle: https://central.sonatype.org/publish/publish-portal-ossrh-staging-api/, which we used to publish android.

There are couple major change:

1. SNAPSHOT version is very limited now. I cannot figure out how to use the publiser API with snapshot. So, the snapshot only uses central-publishing-maven-plugin to test the uber jar.
2. The ossrh API for maven central is now different with limitations as this PR written, see here for details. It also doesn't support deploy-file plugin.
   • the major limitation affects us is that the APIs they provide currently automatically "close" the staging repositories, so that it cannot be changed afterward.
   • The previous way we used is to open the staging repo, and upload different classified JAR and then close it will not work now.
3. The central-publishing-maven-plugin doesn't seems to support publish multiple jar with different classifier,so that I worked around it by bundle all those jars together locally and then use the publisher API to upload the whole bundle.
4. The gradle plugin io.github.gradle-nexus.publish-plugin also affected by the limitation mentioned above, so that the publish and release has to be in the same call now. Failed to findSonatypeStagingRepository with the new configured URL to maven Portal gradle-nexus/publish-plugin#379
5. GPG API is a bit different now. gpg: signing failed: Inappropriate ioctl for device keybase/keybase-issues#2798 and https://maven.apache.org/plugins/maven-gpg-plugin/usage.html as they updated the needed environment variables for GPG@v2.

As a result:

• Starts to use the latest Ubuntu version, since the maven version required is not available from the old Ubuntu version
• Side affect of the new ubuntu is that it comes with new GPG, and updated the API to adapt the change from the new GPG as mentioned above.
