Subject: [PATCH] General: Introduce HTML classes in `get_calendar()` for
 easier CSS targeting:

* `.wp-calendar-table` for the `<table>` element.
* `.wp-calendar-nav` for the navigation wrapper.
* `.wp-calendar-nav-prev` for the previous month link.
* `.wp-calendar-nav-next` for the next month link.

Replace `#prev` and `#next` HTML IDs with `.wp-calendar-nav-prev` and `.wp-calendar-nav-next` classes.

Props sabernhardt, BackuPs, audrasjb, jorbin.
Fixes #39763.
