Description:

It would be useful if there was a way to either set the desired version of pip, or to stop it from being updated to the latest version.

Justification:

I need to make use of the PIP_USE_FEATURE=truststore ability which is currently broken in the latest version 24.1 of pip, but worked fine in 24.0 and earlier.

My Python workflows are now broken until a new version of pip is made available as I can't seemingly stop this action from always updating pip to the latest version.

Are you willing to submit a PR?

Yes.
