fix: declare prism-react-renderer as a direct dependency

It was being imported from components/liveHighlight.tsx,
components/prismLanguageSC.ts, and components/prismTheme.ts but only
resolved as a transitive of react-live-runner. Pinned to 1.3.5 because
the code uses the v1 API (default Highlight export plus named Prism
and Language exports), which v2 dropped.

Also clean up two oxlint warnings in prismLanguageSC.ts: switch the
keyword sort to Array#toSorted and drop a redundant empty export.
