Media: improve the `human_readable_duration` function and tests. 

Improve the `human_readable_duration` added in #39667:
* Remove upper limit.
* More resilient handling: remove negative prefix, trim.
* Correct @since to 5.1.0.
* Adds more test cases and improve inline docs.

Props birgire.
Fixes #39667.
