Feature Request: Add Steam as External OAuth Provider

[RiChrisMurphy]

Unsure of how difficult it would be to add, but I figured I'd ask. :)

I think this is a great Feature Request. You should start an issue in the gotrue repository so people can further discuss it. And people from the auth team can see if this is doable.

Even though I don't think there are a lot of Steam devs, the ones that are out there would LOVE an easy way to set up auth because right now it's a big pain

There are dozens of us, dozens!

I just found this after Googling for a way to handle Steam. So, yeah.

I would like to promote my own suggestion https://github.com/orgs/supabase/discussions/30100 , because it include Steam and any other provider.

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.
