Tweak pywin32 vers

[jmackay-godaddy]

The library pywin32 is being flagged by GitHub Dependabot with an integer overflow vulnerability which can be used by an attacker to crash the process in question. docker-py has a conditional dependency on the fixed version 227 of this library. This PR upgrades that to 228 for python2 users and upgrades to 301 (which fixes the security issue) for python3 users.

@jmackay-godaddy I think this PR duplicates #2943 more or less

Sure if you dont care about python 2 support go ahead use the other PR. This version retains Python2 support.

As the author of #2943 I'm fine with this. Not generally in favor of keeping Python 2 around any longer, but this might make sense for most people.

Hi! Thanks so much for your PR and apologies for the delay in review. A fix for this has been merged and we're planning to issue a new release containing it soon. For context, changes similar to yours were done in #3004 to address some CI changes in the repo, which blocked merging of your PR as-is, and given the delay on this, we wanted to be respectful of our contributor's time and not require you to rebase + re-review.
