Add support for CapybaraBR

It runs UNIT3D, so it should be similar to the others. I'm happy to run some test curls as needed.

This tracker is not like other UNIT3D trackers. usually, this should return your user stats, but it returns a 404. You can test this yourself, and try to find the actual api endpoint.

curl https://<capybara URL>/api/user\?api_token\=<Your API Key>
