firefox: remove test reporting from the workflow

The test reporting github action fails to upload the test results
with the following error:
"HttpError: Resource not accessible by integration"

The tests are still executed, and their overall status is still
reported as part of the test job, but the test report itself
isn't uploaded amongst the workflow artifacts.
