Issue:
Use Github Actions instead of Travis on push
**How would this feature be useful?**
<!-- Describe any use cases this solves or frustrations it alleviates.   -->
We could use native Github Actions to do the same push-triggered verifications that we currently do using Travis CI.

It would remove Travis from our flow, removing one more moving part, and keeping all committing actions within Github, which seems more reliable to me.

It would also make it easier for us to in the future integrate other actions, such as doing a lot of housekeeping on a release.  For example on a Github release, we could rebuild the docs and publish them, and submit to PyPI.

**Describe the solution you'd like**
<!-- If you have an idea of how to do this, write it here! -->
I have a branch in my repo up and running using Github Actions that currently replicates our Travis CI
push-triggered verifications and tests.
https://github.com/itsayellow/pipx/tree/github-actions

**Describe alternatives you've considered**
<!-- If there's some workaround or alternative solutions, let us know. -->
We don't strictly speaking **need** to do this, the current Travis verifications work.  But I thought this might conceptually be simpler, and thought I'd submit it for discussion since I have it completely implemented and it would be ready to drop in now as a PR.

Closes #440 

This replicates our Travis CI on-push verifications and adds a macos target.
