Release 0.50.0

[agx]

@samcday preparing a release as distros are hitting the gnome-session changes. Happy to let you handle it.

Hm, COPR is down for maintenance at the moment. Impeccable timing 😅

But actually, I'm gonna hold off on cutting the 0.50.0 tag a little longer. Wanna pull Debian's downstream patches up here first.

I don't think you have anything more to pull in, most (if not all) of those have been merged already IIRC; oh wait yes, there's still the bump to nix 0.30, which is just a one-line change in Cargo.toml.

@agx thanks for getting the ball rolling. I was gonna try and squash+merge your PR, but it's presently missing an updated Cargo.lock that includes the version bump, which is upsetting the (--locked) COPR builds. I'll close this out and manually merge + amend and poke the release "machinery" (such that it exists here 😅) now.
