Manifest bump ipython to new version will fail the test

uv.lock is updated by running uv lock --upgrade-package ipython. The problem was found and redirected from #6694

The problem can not manifest by updating the ipython, the failed test is:

I track to ipython/ipython#13268, and find it relates to the VIRTUAL_ENV which @danielhollas you may adapted a bit in ci? Any idea?

We already have a workaround for this that's only applied for python 3.9, and related to setup-uv action.

I suspect you're triggering this even for Python. 3.12 because you have an old uv version locally. I will need to think about if / how to enforce minimum uv version.

I think this PR is not needed, we're just waiting for a new setup-uv release and then we'll be able to drop the existing workaround.

As you mentioned, it is the problem with my local uv version. Thanks for help.
