Update java formatter sbt plugin (#8543)

Add a local clone of javaFormatter plugin. The upstream is not maintained anymore. And we need to update it to use the newest Google java formatter because the old one, that we use, cannot format sources with Java 8+ syntax.

# Important Notes
Update to Google java formatter 1.18.1 - https://github.com/google/google-java-format/releases/tag/v1.18.1
