www/ruby-actioncable61: update to 6.1.5.1

## Rails 6.1.5.1 (April 26, 2022) ##

*   No changes.

## Rails 6.1.5 (March 09, 2022) ##

*   The Action Cable client now ensures successful channel subscriptions:

    * The client maintains a set of pending subscriptions until either
      the server confirms the subscription or the channel is torn down.
    * Rectifies the race condition where an unsubscribe is rapidly followed
      by a subscribe (on the same channel identifier) and the requests are
      handled out of order by the ActionCable server, thereby ignoring the
      subscribe command.

    *Daniel Spinosa*

*   Truncate broadcast logging messages.
