[BUG] CI does not catch missing copyright or license on new files

[jlowe]

One of the CI runs on #2559 should have failed due to a missing copyright and license header on a source file but it did not. We should use something like apache-rat-plugin to catch this error of omission in CI.

@pxLi can this be addressed with the common build repo?

Yes, this could be a good shared action usage to verify the license header change.

I will create another ticket in common repo.
