Sync Checkstyle integration test (#999)

Summary of changes:
- Update the set of expected changes for compatibility with the latest
  features, except for the `ErrorProneRuntimeClasspath` check.
- Test against version 10.12.7 rather than 10.13.0.
- Omit the targeted tag from file names, so that similar upgrade PRs can be
  tested using an `/integration-test` GitHub comment.
