Description

Added a GitHub action that updates aur/forgit when a new release is published. I've also mentioned the AUR packages in the README. This closes #311. @wfxr could you please upload the required secrets for this:

AUR_PRIVATE_KEY: A private ssh key for the AUR AUR_USERNAME: sandroid AUR_EMAIL sandroid \<at> posteo \<dot> net

Once this is done I'll give this some testing and mark it as ready for review.

I could not test this directly with the secrets uploaded to this repository, because the workflow would need to be in the master branch, but I've successfully tested it using act. This works as intended and is ready to be merged.
