Make it more obvious when a user is logged in as [email]@accounts.google.com or similar #268
Description
I've been troubleshooting Globus Group membership and access to the Garden creation form by looking at the user's email in the dropdown from the main navbar. But it appears that if a user logs in via Google SSO, their identity is [their email]@accounts.google.com and that needs to be separately added to the Globus Group. Ideally we can make it so that we just have to add one variant of an email to the group. But failing that we should display the full identity the user is logged in as to make it clear if we need to add the variant.
