TheTask.WaitAsync(TimeSpan, TimeProvider, CancellationToken) method documentation had an inconsistency where the parameter description fortimeout mentioned that aTimeoutException would be thrown when the timeout expires, but this exception was not listed in the method's exceptions section.

Before:
The exceptions section only listed:

• ArgumentNullException
• OperationCanceledException

After:
Added the missingTimeoutException with the description: "The timeout expired. This exception is stored into the returned task."

This change ensures consistency between the parameter documentation and the exceptions section, making it clear to developers that they need to handleTimeoutException when using this method.

The fix follows the same pattern used for other timeout-related exceptions in the codebase and maintains consistency with similarWaitAsync method overloads.

Fixes#11190.
