Invalid `address` claim

Currently the generated address claim is a simple string:

{
  "at_hash": "yrd7IU9fctVw0XFZZYv9pA",
  "aud": "rMhnu1unh63zh3sovnRngb7oyI8kQDq6ismeL1Y5WW",
  "sub": "admin",
  "address": "12 foobar street, 1234 Foobar City, NP",
  "auth_time": 1743704040,
  "iss": "https://auth.nubla.io",
  "exp": 1744393962,
  "iat": 1744390362,
  "nonce": "oJjRElLlkX"
}

However the OIDC core spec indicate that it should be JSON object: https://openid.net/specs/openid-connect-core-1_0.html#AddressClaim
