New ability to query user profile custom fields

We've recently added two new fields to the users object, making it easier to query and manage custom fields in the user profile:

1. custom_field_metas: Retrieves metadata about the custom field, including its type, description, and whether or not it is editable
2. custom_field_values: Fetches the values users input into the custom field

The example below retrieves the custom fields' type, description, id, and editability using the custom_field_metas field. It also retrieves the fields' meta ID and value using the custom_field_values field.

query {
  users (ids: 1234567) {
    custom_field_metas { 
      field_type
      description
      id 
      editable
    }
    custom_field_values {
      custom_field_meta_id
      value
    }
  }
}
