Use --force-reinstall in integration test and skip wheel

[abravalheri]

Summary of changes

In integration test:

• Replace pip install -I with pip install --force-reinstall
• Do not install wheel as it is no longer a build dependency (it also no longer gets automatically installed in the build env in regular workflows).

Closes #4564

I re-ran the failed jobs for v72.2.0, since the release didn't go out as planned, and it succeeded.

Because the issue is intermittent, we'll want to keep an eye out to see if it happens again. Presumably this change will fix the issue. Thanks for working on it!
