Improve dev installation documentation #14755
Description
The current instructions for installing the dev version of matplotlib (specifically in the dev docs section here: https://matplotlib.org/devel/documenting_mpl.html) do not explicitly state that you need to uninstall the conda/pip version of matplotlib first (and maybe several times), before installing the dev version. Not uninstalling first can lead to really unhelpful and confusing errors, so it would be good to include that information in the documentation

This issue has been marked "inactive" because it has been 365 days since the last comment. If this issue is still present in recent Matplotlib releases, or the feature request is still wanted, please leave a comment and this label will be removed. If there are no updates in another 30 days, this issue will be automatically closed, but you are free to re-open or create a new issue if needed. We value issue reports, and this procedure is meant to help us resurface and prioritize issues that have not been addressed yet, not make them disappear. Thanks for your help!

Sorry you didn’t get a response for so long @shanosborne!
I’m pretty sure these days when you install from source, pip automatically uninstalls any existing Matplotlib version. Please comment or re-open if you think I have that wrong.
