Convert CI to GitHub Actions

Context

Travis is removing its free tier for OSS projects, so this should be built with GitHub Actions instead, which is not going to add additional cost.

I would expect this to be one of the easier projects to convert given that Docker isn't used in the build.

Can I try this?

[alexellis]

Yes please use the approach from k3sup and read the contribution guide before starting. Each commit needs to be signed off (not GPG)
