Whitelist Toolkit Release Managers (#234)

# PR Description
The `github.event.pull_request.author_association` in the "Prevent
Unauthorized Version Updates" workflow was returning inconsistent
results by saying that MEMBERS were CONTRIBUTORS. This PR moves away
from `author_association` in favor of a whitelist text file containing
the GitHub usernames of authorized toolkit release managers.

A toolkit release manager has the following special permissions:
* Can change the version of an existing toolkit
* Can delete an existing toolkit 
* Can rename an existing toolkit
