[web][native][keyserver] Flip the switch to enable specialRole field
Summary:
This diff will need to be landed at the same time as a release/codeVersion bump so things don't break in developer's local environment.
Will send message in Releases channel when ready.
Depends on D11188
Test Plan: Have a local "do not land" diff that does this locally and things work as expected.
