Check if translation files need to be updated in CI
ATM translation files are getting outdated pretty fast and need to be updated manually.
Weblate needs those files to be updated to provide ability to translate new/edited strings.
CI could check if in-code strings changed in MR and fail test if corresponding string wasn't updated/added to pot files.
Docs should probably include some info how contributors could update those. AFAIK It's automated anyway, someone just needs to run script after changing strings.
Possibly can be implemented just by running update script in CI and checking if pot file changed. If it changed it should be updated in MR.
