fix(providers): Update Foursquare profile callback + API version

[MatyiFKBT]

☕️ Reasoning

The Foursquare provider does not work in its current form, because their api returns in the following form:

{ "response":
  { "user": 
    { "id": "...",
      "email": "..."
    }
  }
}

This pull request fixes it and uses the same form with NextAuth v4 as in @auth/core (see here).

I also bumped the apiVersion property to match @auth/core, let me know if I should test it with a newer version, and maybe open a new PR to bump the version,
