Not sure if this is still needed: https://github.com/pandas-dev/pandas/blob/main/gitpod/gitpod.Dockerfile#L38C5-L38C45
I would go ahead and update the gitpod as well - no reason to still be using setuptools anywhere in our code base I think that the file [`gitpod.Dockerfile`](https://github.com/pandas-dev/pandas/blob/main/gitpod/gitpod.Dockerfile#L38C5-L38C45) is not being used. Since it's not being called here: https://github.com/pandas-dev/pandas/blob/main/.gitpod.yml#L9C3-L9C19  (but of course, I could be wrong). 

Plus it seems that there is some pending work for gitpod: https://github.com/pandas-dev/pandas/pull/54046

Maybe updating gitpod could be done on a separate PR?
