Turn process into a github workflow

[cognifloyd]

Until microsoft/botbuilder-python#1467 is resolved, we will need to maintain barely forked wheels. Instead of re-building the wheels from scratch (to maintain full compatibility with current version), we:

• remove any existing unpacked directories rm -rf bot*
• download the wheels from pypi
• unpack each wheel with wheel unpack bot*.whl
• commit the unpacked files (to allow traceability of what we changed)
• adjust the dependencies in *.info/METADATA
• commit the changes
• repack the wheel wheel pack *
• tag the commit
• make a release on github from that tag and upload the wheels as the artifacts for that release.

This should probably be a github workflow. For now, I'll do it manually, but hopefully we won't need to do this again. Hopefully we can just archive this repo soon.
