`team-windows` should be requested for reviews whenever a windows test file
or the reg.py execution module and accompanying reg.py state file are edited.
The CODEOWNERS file documentation for GitHub says they use a .gitignore-style
file matching pattern. However, since [tamarack](https://github.com/rallytime/tamarack)
is doing the actual team review requesting work, it uses Python's fnmatch lib.
This PR updates some of the file matching patterns to use fnmatch more specifically
and will improve the review requests to be more accurate and increase the number
of automatic team review requests.
