Introduced GitHub Actions initial workflow

It runs on the latest ubuntu, install gcc and runs ./build.sh It was generated using GitHub Copilot

To be sure I am understanding the Action. Whenever a push or pull is attempted, the linux build is executed. If the build fails, does the invoking push or pull fail? Thanks

Whenever a push is attempted, github will trigger a job that will check the Linux build still works. It will not block the push. It could auto-reject a PR.

I'd recommend to enable Require status checks to pass before merging on main.
