#beta blocker triage

I added a hook to allow additional tokens. I have added a patch. I have not updated the MR. I'm still new to contributing to Page Manager.

  /**
   * Returns available context as token data.
   *
   * @return array
   *   An array with token data values keyed by token type.
   */
  protected function getContextAsTokenData() {
    ...

    $this->moduleHandler->alter('page_manager_context_as_token', $data, $contexts);

    return $data;
  }
