Automate releasenotes to each release

As someone that uses Ampersand directly from the releases page, it is hard to find the releasenotes. I suggest to add the releasenotes as a separate asset to each release. This can be done automatically :)

I don't understand.. the release notes are there with the release:

True, but these are only the notes of THIS release. In earlier releases, a link to the releasnotes was provided:

However, since we changed from branch master to main, these links are all broken.
My idea is to add the releasenotes.md file as an asset. Just for convenience.
