fix(github): rename service to github-actions

[ArturKlauser]

The coveralls API refuses to accept submissions with service=github, but accepts
submissions with service=github-actions.

I fear that your commit docs(circleci): token is now required has broken your circleci tests for PRs. They all fail their last stage, sending data to coveralls with:

CoverallsException: Not on TravisCI. You have to provide either repo_token in .coveralls.yml or set the COVERALLS_REPO_TOKEN env var.
ERROR: InvocationError for command /root/project/.tox/coveralls/bin/coveralls --verbose (exited with code 1)

Looks like I just forgot to check the button for having CircleCI pass secrets to PR builds -- tests pass upon re-running.

This LGTM as well -- I'll get this deployed as v1.9.2. Let me know if you continue to have any issues!

[ArturKlauser]

Thanks, v1.9.2 works like a charm now.
If you ever run across why the coveralls API rejects service='github' let me know, I'm curious.

@ArturKlauser you may be interested to know that the Coveralls API seems to now be accepting service='github' -- as of my testing of #216, I've found that this now works perfectly fine.

I still have no idea whatsoever... but (just guessing here) maybe it was a bug they finally fixed?

[ArturKlauser]

Interesting. Or maybe it is the added service_number that you're now sending that was expected on the server side.

[TheKevJames]

As far as I can tell, the service_number is only parsed for parallel builds -- I tried a non-parallel build with service='github' and everything seemed to work just fine. May have missed something, of course!
