Setup devel server as a Github Actions self-hosted runner

I do not have permissions to view or modify anything in the Settings so I cannot perform this action. But it would be great to setup the gEAR (and maybe NeMO) development servers as self-hosted runners so we can have automated testing occur.

I am willing to write the Github Actions workflow script to get it working

Not planning this for now

This would have applications if we are testing the codebase itself, or if we need to dynamically checkout the code onto the devel server upon triggering the Github Actions workflow. Rather, if we point to the devel URL in the tests (and the server is up) then we can use Github Actions to hit that URL and perform the tests
