Move py3-codespell to community
We rely on Codespell for the CI in some of our projects downstream in postmarketOS. This means we have to use Alpine Edge as it isn't present in stable releases, which works most of the time but can be a problem when there's a major rebuild in Alpine (like the recent Python 3.12 one). As such, it would be useful for us to have this moved to community so it can be made available in future stable releases.
Additionally, the Alpine package (py3-codespell) has been in testing for over three years now (7515cdbb) so I think it should be okay to move it to community and subsequently include it in stable releases by now.
