RFR: 8345888: Broken links in the JDK 24 JavaDoc API documentation, build 27

Tue Dec 10 11:48:11 UTC 2024

Please review this trivial change fixing a broken link in `PresentationDirection.java`

The contents of the links are identical, I used the [wayback machine](https://web.archive.org/web/20210511075617/https://ftp.pwg.org/pub/pwg/standards/temp_archive/pwg5100.3.pdf) to view the old content.

TIA
