Move validation test suite, phpstan to GitHub Workflows

- Perform a shallow clone of submodules analyzed in validation
  test suite in GitHub workflows (should take around 30 seconds)
- Switch badge in README.md to GitHub Workflows and update default
  branch for badge.
- Remove travis config
- After #385 is merged run_phpstan.sh can remove the separate install
  step (as a followup PR)
- Require a newer phpunit patch version in devDependencies
  Make it harder for contributors to have any inconsistencies with CI
  when running tests (e.g. php version support, fixed phpunit bugs, etc)

 still a ton of work to be done, so at this point, this repo mostly serves as
