Document how to troubleshoot filepath length limit problem when installing scikit-learn on Windows #15911
Description
When installing scikit-learn using the pip installer from the Python install that you get from the Microsoft Store (when typing "python" in a commandline prompt without anaconda/miniconda), I get the following message:
C:\Users\olivi>C:\Users\olivi\AppData\Local\Microsoft\WindowsApps\python.exe -m pip install scikit-learn
