feat(ci): add release template

[AntonioVentilii-DFINITY]

Motivation

We would like to standardize the release notes.

Wait, does that work? I've been looking for years for such a solution and always referred to this SO thread which says there is no such feature https://stackoverflow.com/questions/56798253/release-template-for-github.

@peterpeterparker this PR would be just to structure the notes. My plan is to have it in a workflow/action that is triggered for new releases

Interesting link, @peterpeterparker . The GitHub functionality it references is documented here: https://docs.github.com/en/repositories/releasing-projects-on-github/automatically-generated-release-notes#configuring-automatically-generated-release-notes

So it looks as if, if we were to label PRs, we could automatically populate release notes. E.g. we could make a section called # Frontend and populate it with commits tagged with frontend. I have a lot of questions about how this works but it looks like something worth exploring. At some time. When we have time. 😆
