Top 100
This PR celebrates the upcoming 100k stars for `transformers` by highlighting 100 open-source repositories that use or have integrated `transformers` in their projects.

This list should not be limited to 100 (which we use as a mirror to the 100k stars), so we're looking forward to having libraries that integrate `transformers` open PRs against this document.
_The documentation is not available anymore as the PR was closed or merged._
