[cooker] KDE Frameworks 5.58

It's late in the cycle given the RC is released, but this looks like something worth updating.
Looking at the changelog, it's a load of bugfixes and little else.


If you bump you need rebuild plasma* and all kde apps*.

I think we should be deciding, perhaps in TC-Meeting tomorrow if we can we release what we have Sunday as Final/Public/GA release. Then update KFrameworks after release.

There is one possible constraint against releasing Sunday that I'm aware of and that is that we don't have repos split. Doesn't seem at all like a good idea to release until repos split. But aren't we ready enough otherwise?

Another constraint might be that we don't have a mirrormanager ready, or do we?
