Subject: [PATCH 1/2] fix: revert checkstyle 13.3.0 bump and add Java 17 to
 Jenkinsfile

Checkstyle 13.3.0 requires Java 17 (class file version 65.0), which
breaks the plugin BOM tests that run on Java 11.

This reverts the checkstyle version to 13.0.0 and adds a Java 17
configuration to the Jenkinsfile as requested by @MarkEWaite.

Fixes #215

Subject: [PATCH 2/2] fix: downgrade checkstyle to 12.3.1 for Java 17
 compatibility

Checkstyle 13.x (both 13.0.0 and 13.3.0) requires Java 21 (class file
version 65.0). Downgrade to 12.3.1 which is the last version compatible
with Java 17.

Verified locally: BUILD SUCCESS with Java 17.0.18-tem.
