RFR: 8312098: Update man page for javadoc

Fri Dec 1 17:13:14 UTC 2023

Please review this **forwardport**.

The original issue should've been committed to mainline first and then backported to jdk21, but instead it was [committed in jdk21 first](https://github.com/openjdk/jdk21/pull/130) and almost forgotten to be brought to mainline.

This PR brings the change to mainline just in time: RDP 1 is next week.
