Release stable

AppImage/type2-runtime#121 (comment)

The terms "stable", "beta", "alpha" etc. are just names. Trust me when I tell you that the latest alpha is good for daily use at this point.

Linux distributions tend to only package "stable" releases.

Proposed solution

To avoid user frustration, maybe it would be a good idea to release it as "stable" then?

Either this, or please add a note in the readme that the alpha version is considered stable.
