Check "linked" JH `msgid` with upstream `msgid` in time
When the msgid
in upstream /locale/gitlab.pot
is changed or deleted, the override msgid
in following files would no longer take effect.
/jh/locale/en/gitlab.po
/jh/locale/zh_CN/gitlab.po
/jh/locale/zh_HK/gitlab.po
We need to fetch the changes in /locale/gitlab.pot
automatically, maybe we can create a CI job to implement it. And then we can update the three files above in time.
