Move validation test suite 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.
- After microsoft#385 is merged we can probably start running phpstan in GitHub
  Actions for a single php version and remove .travis.yml entirely
  (as a followup PR)

 This is an early-stage PHP parser designed, from the beginning, for IDE usage scenarios (see [Design Goals](#design-goals) for more details). There is
