Message:

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.
