snap: Update to use core22

[kenvandine]

In theory this should work with the latest gnome extension and core22. Although setuptools wasn't quite doing the right thing.

Unfortunately when I try this and run snapcraft, I get this error:

/root/stage/share: No such file or directory                                   
Failed to execute pack in instance. 

and I have no idea what it means? :(

the more detailed log looks like this:

does this mean that... it's expecting to find a share directory somewhere to copy stuff into and it isn't present? Am I meant to create that or something?
