samples/checkstyle tests failures

[zhumin8]

samples/checkstyle tests started to fail recently (since Nov 2024) with java compatibility error:

Error:  Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:3.2.1:check (default-cli) on project logging-snippets: Execution default-cli of goal org.apache.maven.plugins:maven-checkstyle-plugin:3.2.1:check failed: An API incompatibility was encountered while executing org.apache.maven.plugins:maven-checkstyle-plugin:3.2.1:check: java.lang.UnsupportedClassVersionError: com/puppycrawl/tools/checkstyle/api/AuditListener has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
