pin to ubuntu-22.04 for releases

See #12411

This is an important PR! Going even lower than 22.04 might be a good idea for the release build. As long as rustc is up to date and the Appimage process works, it is good to have a low libc version for compatibility.
I will be waiting for this to be merged to have my PR (generating a .deb file during release) working as well.

actions/runner-images#11101 We can't pin any lower, unfortunately.

So Debian 12 or lower users wouldn't have any way to run the latest Helix release other than Homebrew. Do we?

After they downgrade the CI builder to 22.04, both the Appimage and my .deb should be available from releases and running on Debian 12. The .deb will have a libc6 (>= 2.34) dependency and will therefore not work on lower than Debian 12.
Unless we are allowed to make more changes to the CI run.
We could have a 22.04 image build the AppImage, and for example 20.04 build the binary and .deb, having them available on more systems. But that would be a proposal for the future. For now, lets merge this pin of all the images to 22.04.

Or you can always use my deb build suggestion -> #12453 (comment)
Even if the system is very old, because you just compiled it yourself. But the deb installs all relevant files and can be distributed as a single file.

Curious: have you "re-released" the 25.01 release applying this, so e.g. the appimage from 25.01 can work on Ubuntu 22.04? :) Seems not from the timestamp on the release files? If not, is this something you would be ok doing? (I know several people who came back to me saying the 25.01 was not working and this was the cause) :)

After another bug fix or two we're planning on cutting a 25.01.1 patch release that will include this
