This is the new base branch for the classref translations to prepare them
for the 3.5 release.
This means that the 3.4 class ref translations will likely no longer get
updates, as we can't easily maintain two slightly different branches on
Weblate.
(cherry picked from commit aac4e36149)
It's useful context for translators but it generates very spammy diffs whenever
a line is added or removed, changing the comments for hundreds or thousands of
msgids needlessly.
We still have the file names so it's relatively easy to search in file to find
the location of the source string.
(cherry picked from commit dbfe36728e)
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.
