Attach .ipa to the release page

[kamaeff]

Hi!

I want to try Cassette, was hoping to see an IPA on the release page to install it via sidestore without running Xcode to build it, but found none.

It would be nice to have an IPA file as a github release artifact.

If I have time maybe I try to create a PR automating this via gh actions.

For now just built it myself from latest commit in main (61fba23).
I've ran out of app ids for sidestore to check if it runs, but it works in LiveContainer.

For anyone interested, here is my adhoc ipa (rename .zip to .ipa to install): Payload.zip. Actually you should not trust me, so check it out on your own risk.
It is a debug build of Cassette. Cassette.app from xcode build folder is put into .zip archive (and ipa IS zip archive so renaming .zip to .ipa is enough to install it via sidestore or LiveContainer).
