Register user with UserManager ERROR: user-managament::Error: 2554, tokens are missing in the request: [[]]

Hello,
I believe that the "Register a User" example under the UserManager is incorrectly defining the payload properties.

The property for tokens has been changed to user_tokens

Eg.
OLD

let payload = {
    firstName : 'John',
    lastName : 'Smith',
    birthday : '1970-12-23',
    language : 'en',
    password : '',
    tokens : [
      {
        token : '+44 123 9876',
        token_type : 'phone_number',
        isPrimary : true
      },
      {
        token : 'example@example.com',
        token_type : 'email',
        isPrimary : false
      }
    ],
    namePublic : true,
    avatarPublic : true
}

NEW

let payload = {
    firstName : 'John',
    lastName : 'Smith',
    birthday : '1970-12-23',
    language : 'en',
    password : '',
    user_tokens : [
      {
        token : '+44 123 9876',
        token_type : 'phone_number',
        isPrimary : true
      },
      {
        token : 'example@example.com',
        token_type : 'email',
        isPrimary : false
      }
    ],
    namePublic : true,
    avatarPublic : true
}

Could you please update the README for new users interacting with the SDK?
