Poem

🐰 A reference once useful now lies in the past,
Its upstream issue closed, no longer to last,
So out with the old link, we tidy with care,
Keeping what matters, removing the wear! 🧹✨

Linked Issues check	✅ Passed	The PR directly addresses the requirements in issue #2524 by removing the stale reference to ory/hydra#3363 from the MySQL migration troubleshooting section.
Out of Scope Changes check	✅ Passed	The changes are narrowly scoped to removing a single closed reference, with no extraneous modifications beyond the stated objective of removing the stale Hydra issue link.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
