Subject: [PATCH] scripts: add `check-trans-update.py`
The `check-trans-update.py` scripts check whether a translated version
of a documentation is up-to-date with the english version.
The scripts use `git log` commit to find the latest english commit from
the translation commit (order by author date) and the latest english
commits from HEAD. If differences occurs, report the file and commits
need to be updated.
