Spec: Add URI parsing for GitHub repositories

[Lamparter]

📄 Description

We should add URI parsing to FluentHub as this will allow native support for handling and opening GitHub repos in FluentHub via the browser, in shell context menu APIs and external apps such as Files and the UWP Companion.

👥 Usage scenarios

Web URI

Here are a few proposals:

1. fluenthub://github.com/{Repo.Owner.Login}/{Repo.Name}
2. fluenthub://https://github.com/{Repo.Owner.Login}/{Repo.Name}
3. fluenthub://openRepository?repo={Repo.Owner.Login}/{Repo.Name}
4. fluenthub://openRepository?repo=https://github.com/{Repo.Owner.Login}/{Repo.Name}
5. fluenthub://{Repo.Owner.Login}/{Repo.Name}

Personally options 1 and 5 are my favourite. What do you think @0x5bfa?

🔙 Backward Compatibility

This does not change APIs and instead only introduces them.
