- Remove library installation instructions from README
- List all features in the library documentation
- Increased MSRV to 1.70
- `GHRepo` now implements the following traits:
    - `AsRef<str>`
    - `Deref<Target=str>`
    - `From<GHRepo> for String`
    - `Ord`
    - `PartialEq<&'_ str>`
    - `PartialEq<str>`
    - `PartialOrd<&'_ str>`
    - `PartialOrd<str>`
    - `TryFrom<String>`
- Added `GHRepo::as_str()` method
- **Breaking**: The `GHRepo::is_valid_owner()` and `GHRepo::is_valid_name()` methods are now regular functions
- Added `is_valid_repository()` function
