Improvement to the built-in github.com rule

[necaran]

The current rule looks like this.

      dotDomain.endsWith('.github.com') && {
        r: new RegExp([
          /(avatars.+?&s=)\d+/,
          /(raw\.github)(\.com\/.+?\/img\/.+)$/,
          /\/(github)(\.com\/.+?\/)blob\/([^/]+\/.+?\.(?:png|jpe?g|bmp|gif|cur|ico))$/,
        ].map(rx => rx.source).join('|')),
        s: m => `https://${
          m[1] ? `${m[1]}460` :
            m[2] ? `${m[2]}usercontent${m[3]}` :
              `raw.${m[4]}usercontent${m[5]}${m[6]}`
        }`,
      },

But there are some problems.

1. Does not support avif and webp.
2. Fails to load images in private repos because a token is required to access the raw URL.

https://raw.githubusercontent.com/USER/REPO/main/IMG.webp?token=XXXXXX

My proposed improvement is like this.

      dotDomain.endsWith('.github.com') && {
        r: new RegExp([
          /(avatars.+?&s=)\d+/,
          /(raw\.github)(\.com\/.+?\/img\/.+)$/,
          /\/(github\.com\/.+?\/blob\/[^/]+\/.+?\.(?:avif|webp|png|jpe?g|bmp|gif|cur|ico))$/,
        ].map(rx => rx.source).join('|')),
        s: m => `https://${
          m[1] ? `${m[1]}460` :
            m[2] ? `${m[2]}usercontent${m[3]}` :
              `${m[4]}?raw=1`
        }`,
      },

You can make life easier by appending ?raw=1 to a blob URL.
It will be redirected to raw.githubusercontent.com, and a token will be appended automatically for private repos.

https://github.com/USER/REPO/blob/main/IMG.webp?raw=1

Another option is to replace blob with raw.

https://github.com/USER/REPO/raw/main/IMG.webp

Make a PR, I mean. Or do you want me to just apply the changes?
