Merge Paperwork update to version 1.2.4 (#46487)

Thanks to @symphorien for this work, which apart from the update itself
includes a few more fixes and cleanups.

I've tested building and running the upgraded Paperwork and while I
haven't done extensive testing on every little feature it seems to work
so far.

The changes also include an addition to fetchFromGitLab, which allows to
specify a group.
