Problem with JWT `iss` value

[widavies]

Currently, the JWT iss claim is set to:

{
  // ...
  iss: "access-token.jwt-signature.stack-auth.com"
}

This domain is not reachable:

$> nslookup access-token.jwt-signature.stack-auth.com
Server:  one.one.one.one
Address:  1.1.1.1

*** one.one.one.one can't find access-token.jwt-signature.stack-auth.com: Non-existent domain

I think iss should be set to api.stack-auth.com?

The reason this is an issue is because 3rd party services assume that the iss domain is the JWKS domain and can be used to authenticate the JWT.
