   *  - name: The translated human-readable short name of the token type.
   *  - description (optional): A translated longer description of the token
   *    type.
   *  - needs-data: The type of data that must be provided to
   *    \Drupal\Core\Utility\Token::replace() in the $data argument (i.e., the
   *    key name in $data) in order for tokens of this type to be used in the
   *    $text being processed. For instance, if the token needs a node object,
   *    'needs-data' should be 'node', and to use this token in
   *    \Drupal\Core\Utility\Token::replace(), the caller needs to supply a
   *    node object as $data['node']. Some token data can also be supplied
   *    indirectly; for instance, a node object in $data supplies a user object
   *    (the author of the node), allowing user tokens to be used when only
   *    a node data object is supplied.
   *
   * @return array
   *   All the different token types.

   * - name: The translated human-readable short name of the token.
   * - description (optional): A translated longer description of the token.
   * - type (optional): A 'needs-data' data type supplied by this token, which
   *   should match a 'needs-data' value from another token type. For example,
   *   the node author token provides a user object, which can then be used
   *   for token replacement data in \Drupal\Core\Utility\Token::replace()
