Google auth is case sensitive

Bug description

From a Customer signing up to EU Cloud (names redacted):

Hello Simon! Just tried to login with an invite an admin sent me. They invited me on [email protected], and I tried to login using my Google Workspace-account which is: [email protected]. This gave me a Server Error (500) on my way back to PostHog, from Google's Oauth. I suspected this could be due to case-sensitivity, so an admin changed the invitation to [email protected] , and then it worked, so just letting you know.

How to reproduce

1. See above

Environment

• [x] PostHog Cloud
• [ ] self-hosted PostHog, version/commit: please provide
