Adding this package to non-gnu ELPA

[gcentauri]

Hello to anyone watching this repository 😄 👋🏽

I would like to get this package included in the NonGNU ELPA package repository. As far as I know, I would just need to submit the source repository to the emacs-devel list and it should be good to go.

However, there's been an push lately to move away from GitHub, as it is not a good/ethical citizen in the free software world. If there are no objections, I plan to fork this repo over to sourcehut or codeberg and serve the package (to ELPA) from there. I understand that people may feel this is a barrier to contributions, so I wanted to give some space for discussion.

Very little of minitest-emacs is work I've contributed to personally, but I use it daily and have an interest in keeping it alive and well in the Emacs ecosystem. Please add your opinions to this discussion, thank you!
