[3.8] gh-101997: Remove stale pip-22.0.4-py3-none-any.whl from the 3.8 branch

[ambv]

This was left over in gh-102244.

• Issue: Upgrade the bundled version of pip to 23.0.1 #101997

There being duplicate wheels present has occurred two times prior to this. Would it be worth adding a test that ensures the correct number of wheels are present?

[ambv]

@edmorley, good idea, I reported gh-109002 on your behalf and made a PR to this effect.

Thank you! :-)
