ci: rename travis -> ci and modify CI docs (#66)

- now that GH Actions are merged, thoroughly tested, and working:
  - rename `travis` dir to `ci` dir instead
  - update `release.md` to remove Travis references and reference GH Actions files instead
    - and just generic "ci build" instead of "travis build"
    - CI is working now, so uncomment/unquote the previous numbers

- leave `cp_to_travis` and `reverse_ssh_tunnel` as is for now, in case Sylvain wants to adapt them to GH Actions
  - I'm not sure they'll work as-is on GH Actions (e.g. `travis_base` won't exist), so they may need further modification
    - (or it may not be possible at all with GH Actions to do reverse SSH)
    - that is beyond my scope since I'm not using these, don't have a bounce host, and am developing on a Mac locally
