docs: regenerate rendered output for SEP-2549

Fixes the failing Render SEPs job:
https://github.com/modelcontextprotocol/modelcontextprotocol/actions/runs/33339583528/job/99332656804

PR #3310 fixed a typo in `seps/2549-TTL-for-list-results.md` without regenerating `docs/seps/`,
so the rendered page still reads `serer` while its source reads `server`.

This makes `npm run check:seps` fail on main branch. Regenerated with `npm run generate:seps`.
