Langs check

[ia]

• Please check if the PR fulfills these requirements

• The changes have been tested locally
• There are no breaking changes

• What kind of change does this PR introduce?
  Autocheck between json files with translations and enabled builds in source/Makefile.

• What is the current behavior?
  If translation is added as translation_LANG.json, then we have not to forget manually add LANG to ALL_LANGUAGES inside source/Makefile.

• What is the new behavior (if this is a feature change)?
  scripts/deploy.sh update with related autocheck.

• Other information:

The test will be intentionally broken just for the demo purposes only. I will revert source/Makefile once I will test the autotest.

I really appreciate this. So putting all jokes aside, just ping me/mention me once you or anyone else will notice any false positive or negative trigger, and I will try to fix any problems with that as fast as I can.
