Problem
Login Hints from a Google Workspace SP don't work.
Solution
Add 'login_hint' and 'LoginHint' as additional supported username hints from SPs.
Context
Google Workspace allows you to configure using an external SSO provider. It offers the ability to provide a username hint for the person attempting to authenticate. SimpleSAMLphp currently only supports 'username' as a URL parameter, but Google only provides options for 'login_hint' or 'LoginHint' to be used.
