[docs] [issue36689] docs: os.path.commonpath raises ValueError for different drives

[Christoph Reiter]

New submission from Christoph Reiter <reiter.christoph at gmail.com>:

Since I just got bit by this despite reading the docs:

https://docs.python.org/3.8/library/os.path.html#os.path.commonpath

It lists various error cases where ValueError is raised but is missing the case where absolute paths on Windows are on different drives and I forgot to handle that:

  File "C:/building/msys64/mingw64/lib/python3.7\ntpath.py", line 631, in commonpath
    raise ValueError("Paths don't have the same drive")
ValueError: Paths don't have the same drive
