[Suggestion] Repos endpoint improvement

[z3db0y]

Hello, I was not sure where to write this issue, so I decided to dump my thought here and hope that somebody would pass it on to the right people. (sorry about that)

I noticed that the /users/user/repos endpoint returns a language property, but I'd like to see another key implemented such as languages or language_details that contains data from the languages_url endpoint. This would be cool to see as currently if a dev wishes to get all the languages of their repos, they would quickly exceed their API rate limit quote (50 public repos, let's say, all of which's languages you want to fetch).

Thanks for reading and I hope that somebody kind enough passes this on to a Github dev/engineer and I would like to hear feedback on my suggestion.
