deps: upgrade pywin32 & relax version constraint (#3004)

Upgrade to latest pywin32, which has support for Python 3.10 and
resolves a CVE (related to ACL APIs, outside the scope of what
`docker-py` relies on, which is npipe support, but still gets
flagged by scanners).

The version constraint has also been relaxed in `setup.py` to allow
newer versions of pywin32. This is similar to how we handle the
other packages there, and should be safe from a compatibility
perspective.

Fixes #2902.
Closes #2972 and closes #2980.
