Move typedoc and react out of runtime dependencies

typedoc is only used by the docs script, but as a runtime dependency its
typescript peer range (capped at 5.8.x for typedoc 0.27) constrains
consumers' typescript version: classroom's Renovate typescript 5.9 bump
produced a lockfile npm ci rejects.

react/react-dom were listed in both dependencies and peerDependencies,
forcing react on consumers of the vanilla entry point. They are now
devDependencies (for Storybook) alongside the existing peer ranges.
