Custom auth providers

[RagnarTheEverchosen]

Hey, I would like to ask if there are any plans to add OpenID 2.0 as a provider.

To be specific I mean the Steam OpenID/OpenID.

I know there has been several similar post on this topic as Steam seems to be a highly demanded provider but up to know I haven't seen a concreate answer if this might come in the future or not.

I attempted a PR for Steam provider support
However, I think the main problem is Supabase's reliability on user emails, so I am not sure if this will (fully) work.
