Fix description of --no-binary to reflect current behavior

[rio767]

Summary

Update the description of --no-binary to reflect behavior introduced in pip 23.1.

Details

The current help text says "Do not use binary packages", which is misleading.
Since pip 23.1, the option prevents downloading binary distributions, but cached wheels may still be used.

Closes #13087

No news entry needed (docs-only change).

Hi @rio767, thanks a lot for your contribution!
It looks like you’ll need to add a news file, and the pre‑commit checks are currently failing as well. Please take a look at pip’s contributing guide for details. If you need any help resolving the errors, feel free to ask.
Also, just a heads‑up that it may take some time before a maintainer is able to review your PR.

Added the news fragment and fixed pre-commit issues. Let me know if anything else needs to be adjusted.
