Move from Travis CI to Github Actions #1221

[kr1st1nagr03g3r]

I had some spare time and use your animations so much, I thought I'd contribute.

I set up a Github Workflow called Install Start Run, which will

• run: npm run build --if-present
  - run: npm test
  - run: npm install
  - run: npm start
  - run: npm run docs

I did not delete the Travis CI, however it could also be done.

Reference: #1221

hey @eltonmesquita can you take a look into this?

Thanks for this and sorry for the way too long time to review it. It's a sound change, but I'll skip it as we'll need some additional GHA work for the new plan I'm working on.
