feat: enable commit bodies in changelog and fixes general warnings and updates (#49)

Allows commit bodies to show up in release notes, this is something I'd prefer as my releases are usually short, and I'd like to see these as I don't use pull requests as often, and often miss the context, as I don't link to commits currently.

Also fixes a lot of warnings and reintroduces failing tests, still not perfect, but better than before.
