chore: add is_email_validated and is_email_already_taken in ProfileAttr

[shadowsheep1]

Short description

This PR allows the configuration of is_email_validated and is_email_already_taken with config.json.

How to test

Try to set config.json as below:

{
  "profile": {
    "attrs": {
      "name": "Gian Maria",
      "is_email_validated": false,
      "is_email_already_taken": true
    }
  }
}

and login. The profile you got during the login phase comes with the corresponding values of is_email_validated and is_email_already_taken.
