Drop `.git` in URIs

[MarkLodato]

The generated URIs append .git to the end, but this is wrong.

        "uri": "git+https://github.com/ianlewis/actions-test@refs/heads/main.git",

I suggest removing this altogether. (Another option would be to move it before the @, but that doesn't seem to have any value.)

Yeah, I noticed that and was thinking of moving .git before the @ but I couldn't find any good examples of URIs like this. Removing it probably works just as well.
