Pasting a calendar link to a page doesn't embed the calendar any longer

Issue Summary

Our documentation, Embed calendars on Confluence pages, says that we can embed a calendar into a page by simply pasting the calendar's link in the body of the page, but this no longer works.

Steps to Reproduce

1. Create a calendar
2. Go to the calendar and copy its link using the ellipsis button > Embed
3. Edit one page and paste the calendar's link on the page

Expected Results

The calendar's link would convert into a Team Calendars macro for this calendar and when the page is saved it would display the calendar.

Actual Results

After pasting the link on the editor it is not converted, and when saving the page the calendar will not be displayed, just its link.

Workaround

Select the Team Calendars macro from the macro browser and add the calendar using the macro instead of pasting the link.
