Add Test Analytics

[katia-sentry]

Hey there! I work over at Sentry on the Codecov team and we've set a goal for adding some of our new features to open source repos already using Codecov. I saw this repo using Codecov, and it seemed like a good fit :)

What is the new features?

Test Analytics is a new Codecov feature providing insights into your test suite's health.

• Overview of test run times and failure rates across branches.
• PR comments listing failed tests with stack traces for easier debugging.
• Identification of flaky tests from main in PR comments, enabling quick retries and fixes.

Looking forward to your feedback!

I don't think we want to run pytest here. Our test-doc run is:

test-doc: sample_data testing_data
	$(PYTESTS) --doctest-modules --doctest-ignore-import-errors --doctest-glob='*.rst' ./doc/ --ignore=./doc/auto_examples --ignore=./doc/auto_tutorials --ignore=./doc/_build --ignore=./doc/conf.py --ignore=doc/sphinxext --fulltrace

And we already produce a suitable junit.yml I think... we probably just need to upload the one we already create

@katia-sentry let me know if you want me to push directly to adapt or if you want to iterate a bit. Feel free to add your name to doc/changes/names.inc plus a changelog entry in doc/changes/13225.other.rst with the :newcontrib: reST directive as well!

@larsoner appreciate your review and feedback. I made the requested changes. Let me know if I missed anything, or more iteration is required. Thank you!
