Hook up pytest results for publishing on each Github Action

Summary:
The pytorch test-infra jobs already support submitting test reports for display on a job.
This can improve the user experience when there's a problem with the CI.

Right now this is just for python tests, but cargo also supports the JUnit xml format, so we
can add that later too.
