Since we bundle the whole files in the editor binary, they actual impact the
binary size needlessly.
Automate it via `make merge`.
(cherry picked from commit 6fb47a271f)
The files are directed copied from the version which was merged in `3.x`
together with the translations from Weblate.
For future commits we can do cherry-picks from `3.x` to `master` like usual
for the editor translations.
