DOC: replace dolphin license RDF block with prose attribution

Pedrom2002 · Pedrom2002 · commit 3954e0e8c854 · 2026-04-20T20:56:28.000+01:00
The inline cc:License RDF in the dolphin example was never rendered and only acted as attribution metadata, so the upstream URI namespace (web.resource.org -> creativecommons.org/ns# -> whatever comes next) is ongoing maintenance for no reader benefit. Replace the block with a single plain-text credit line naming the author and the Public Domain status. Addresses review feedback on #31540. Refs #30306.
