actions: release: Use GH cli instead of hub

hub is now deprecated, which has been causing issues with our release
process.

Let's move to the GH cli (https://cli.github.com/manual), and unblock
this release.

**NOTE**: This commit is purposefully not touching anywhere else hub is
used, as that would require more time and investigation to do the
switch, and right now we just want to unblock the release.

Fixes: kata-containers#8286
