Issue #, if available:

Description of changes:

Summary

Reverts the aws-lambda-java-serialization dependency from 1.3.0 back to 1.2.0 across the runtime interface client and test modules, and bumps the RIC version to 2.10.1.

Changes

Dependency revert (serialization 1.3.0 → 1.2.0):

• aws-lambda-java-runtime-interface-client/pom.xml
• aws-lambda-java-tests/pom.xml

Version bump (RIC 2.10.0 → 2.10.1):

• aws-lambda-java-runtime-interface-client/pom.xml
• aws-lambda-java-runtime-interface-client/test/integration/test-handler/pom.xml
• aws-lambda-java-runtime-interface-client/README.md
• README.md

Changelog:

• Added 2.10.1 release entry to RELEASE.CHANGELOG.md

CI improvement:

• Updated aws-lambda-java-tests.yml to also trigger when aws-lambda-java-runtime-interface-client, aws-lambda-java-serialization, or aws-lambda-java-events change
• Added workflow_dispatch for manual triggering

Testing

• Ran aws-lambda-java-tests locally (47 tests, 0 failures) against RIC 2.10.1 with serialization 1.2.0
• RIC installed locally with mvn install -DskipTests

Target (OCI, Managed Runtime, both): both
