Use checkstyle for Java 11

[MarkEWaite]

Use checkstyle for Java 11

• Use checkstyle 10 now that we require Java 11
• Label dependabot pull requests

Testing done

The checkstyle output continues silent when I run mvn checkstyle:checkstyle. Will confirm with ci.jenkins.io as well.

Submitter checklist

• [x] Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• [x] Ensure that the pull request title represents the desired changelog entry
• [x] Please describe what you did
• [x] Link to relevant issues in GitHub or Jira
• [x] Link to relevant pull requests, esp. upstream and downstream changes
• [x] Ensure you have provided tests - that demonstrates feature works or fixes the issue
