PR Summary

• Version Updates in Various Files
  The version identifiers in four different files (online-event/index.asset.php and online-event.asset.php under build/blocks/online-event, and venue/index.asset.php and venue.asset.php under build/blocks/venue) have been updated. This is a routine update to ensure that we are using the most up-to-date version of the codebase.

• Team Contributor Array Updated
  The array listing our team contributors has been updated in the credits.php file. New contributors have been added and some adjustments have been made - newcomers 'nilovelez' and 'carstenbach' have been added to the gatherpress-team array, and 'carstenbach' has been removed from the contributors array. These changes help us recognize the contributions made by different team members.

• Tooltip Content Modification
  In OnlineEvent.js, we've updated the tooltip content to better clarify its meaning. The tooltip that used to say 'Link active for attendees during event.' now says 'Link available for attendees only.'. This change ensures that our tooltip message is clearer and more easily understood by users.

@nilovelez @MervinHernandez if we want to add the online event to the calendar, we are going to need to make that block dynamic, which is fine, but will take a bit of work and like to put it in another ticket for that work. Basically, we can make that a react component like some of the other blocks that listens for changes in RSVP and updates its link from API response. All the pieces for this exist int the Event class and just need to be included in the RSVP response.
