The documentation for delayWhen should not say that it triggers for notifiers that complete without emitting

[roger6106]

Describe the bug

When the change in #3665 was implemented, the documentation was not updated. The documentation still states:

The source value is emitted on the output Observable only when the duration Observable emits a value or completes. The completion of the notifier triggering the emission of the source value is deprecated behavior and will be removed in future versions.

Expected behavior

As that behaviour has been removed, the text should be updated to remove the text that's complete (or alternatively, clarify that previous versions behaved differently):

The source value is emitted on the output Observable only when the duration Observable emits a value or completes. The completion of the notifier triggering the emission of the source value is deprecated behavior and will be removed in future versions.
