RFC: Add (optional?) entry for mod GitHub repo to mods.json

[GeckoEidechse]

Having the GitHub repo linked in there would help with automations that compare Thunderstore package with GitHub repo to check for modifications etc

This would change

{
    "Fifty.mp_frostbite": {
        "DependencyPrefix": "Fifty-Frostbite",
        "Versions" : [
            { 
                "Version": "0.0.1",
                "Checksum": "8cf111c9ac2ab1521677769702e10be4db8d47c0eca16bda197aceb895cf2b5c"
            }
        ]
    }
}

to

{
    "Fifty.mp_frostbite": {
        "DependencyPrefix": "Fifty-Frostbite",
        "Repo": "https://github.com/some-user/some-repo",
        "Versions" : [
            { 
                "Version": "0.0.1",
                "Checksum": "8cf111c9ac2ab1521677769702e10be4db8d47c0eca16bda197aceb895cf2b5c"
            }
        ]
    }
}

I'm not sure if we should make the key optional or not as maps might have an issue in general with being hosted on GitHub due to their file sizes.

Agreed.
