Copying po/docbook files to repositories nightly

>Opinions? Comments?

So our releases will end up a 1:1 with a git tag? That would be
super-duper amazing for many cleanup things, including the security
aspect  +10000

What's the plan for stable branches?
We'll either need to port all active stable branches at the same time
or we will have to make sure releaseme either has multiple branches or
a runtime toggle.

>My plan would be to enable this scripts over Akademy

FYI:
Plasma beta is tagged Thu 2022-09-22
Plasma 5.26 is tagged Thu 2022-10-06

Akademy is in the middle of those.
I don't see how there can be too much fall-out so it's probably fine,
but if we are expecting lots of fixes to be needed that's not the best
timing from our side.
