[jessebot]

Describe the feature you'd like, and why

We need to finish writing the appimage release process so that we can use it in the brew packaging. Some of it has been started here:

But I never finished actually testing it. It should work for at least macos and debian though, so we probably need testing processes for that too 🤔
