This is a typo, you mean PO_FILE, not POT_FILE.

Correct here.

This looks OK to me, FWIW in the version I have on my branch I tried to
munge some of this a bit more. So the diff between my (-)/yours (+) is:

So yours has the "Faroese translations for Git package" (good), but I
also omitted/corrected some of the headers. See 72ed0c8b2e6 (i18n:
migrate to line-number-less i18n workflow, 2022-04-03) in my fork.

This version is also fine, but just in case you wanted to steal
something from it...
