Update test suite (#2181)

* pyscript.web tests pass with upytest.
* Refactor of old integration tests to new Python tests.
* Added comprehensive test suite for Python based `pyscript` module.
* Add integration tests to Makefile (and CI)
* Remove un-needed upload action.
* Ensure fails are properly logged as an array. Remove the explicit test step, since this is already built into the build step.
* Bump polyscript.
