Fix incorrect deprecation notice on Multimedia Timers page

The deprecation notice on multimedia-timers.md incorrectly referenced
Joysticks and Windows.Gaming.Input Namespace instead of Multimedia Timers
and Multimedia Class Scheduler Service. Updated to match the correct
boilerplate used by all other pages in the Multimedia Timers section.

Fixes ADO #543978

-\[The feature associated with this page, [Joysticks](/windows/win32/multimedia/joysticks), is a legacy feature. It has been superseded by [Windows.Gaming.Input Namespace](/uwp/api/windows.gaming.input). **Windows.Gaming.Input Namespace** has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use **Windows.Gaming.Input Namespace** instead of **Joysticks**, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.\]

 The multimedia timer services allow an application to schedule periodic timer events — that is, the application can request and receive timer messages at application-specified intervals.
