Create a smaller review team for general code reviews (#16975)
Code reviews should primarily be assigned to @SaschaCowley and I currently, however we need to maintain a general GitHub team for developers.
Currently reviews are being auto-assigned to the whole NV Access developer team, where their input is only necessary on certain changes.
Description of approach
A new team has been created for just being assigned to NVDA code reviews.
Other NV Access developers still have write access to the repository, and can have a manual review requested where appropriate.
