Add an option to show events details on the Team Calendars UI

On the new Team Calendars UI, the events are showing up on the days slots, but you have to click on the "+ more" events to show the other events, while on the old team calendar view, they all would show up.

Also, when you create an event, it only shows the title option for event, it no longer shows the event details.

For example:
Title: Out Sick
Who: User

Now on the new Calendar UI it only shows the title "Out Sick", on the old calendar it would show up the "User:Title" for the event Out Sick.

This suggestion is to bring it back, as on some use cases, it is heavily needed to know who is on leave and why, without having to go on extra clicks for all events on all days.

As a workaround, the old UI still can be seen on the https://<instance>.atlassian.net/wiki/calendar/mycalendar.action URL and on the Team Calendar macro inserted on a Confluence page.
