test(action): run tests in parallel

- when running all tests at once in CI in GitHub, the system was
  running out of disk space
- with debug code, the problem disappeared, so it seems like some
  race-condition
- to solve this problem, and also speed up the testing (the whole test
  suite takes like 25 minutes to run) we break the tests into multiple
  smaller parts to run in parallel in separate runners
