`no-ssl-verify` for `grant-migrator-role` ?

## Description
GHES 3.7.7 -> Github.com

I am trying to run `grant-migrator-role` but it is failing with the following error due to cert name mismatch on GHES.

There is `no-ssl-verify` option for `migrate-repo` and `generate-script`, should there be one for `grant-migrator-role`?
