Tested it. New translations appear correctly. Looking through them, I couldn't find grammatical errors either

@kanasznagyzoltan : Could you please create a version of this PR for our main branch as well? This was unable to be ported automatically (see above error), so it will have to be done manually. Otherwise, the changes you've made will only be in 8.1 and will be missing from 9.0.
