Log in with Steam

🚀 Feature

Allow for logging in with Steam or add generic OpenID 2.0 support which Valve uses
I was ready to adopt SuperTokens for my gaming application but currently it's a no go because it lacks Steam support

We already do have generic OAuth 2.0 + OIDC provider support: https://supertokens.com/docs/thirdparty/common-customizations/sign-in-and-up/custom-providers

But im keeping this issue open cause we don't have steam in built (however it would be very easy to add it via the generic provider anyway)
