To include contributor's avatar property to /repos/{owner}/{name}/contributors

[claytonchew]

Describe the feature

Would it be too much to add one more property avatar to /repos/{owner}/{name}/contributors?

Motivation: Getting each contributor's avatar would require fetching individually, i.e. /users/{username}. It would be nice not having to do that.

I'll submit a PR soon for your consideration. Thanks.

Avatars are linkable as https://github.com/{username}.png (example).

Have you tried it?
