docs: refine reap adopter entry and add to docs site

- ADOPTERS.md: rename "Reap" -> "reap" to match brand casing, and
  update the use-case sentence to describe HyperFrames' role inside
  reap (matches the HeyGen/tldraw convention on this page).
- docs/community/adopters.mdx: add reap card to the Production
  CardGroup so the hosted adopters page at
  hyperframes.heygen.com/community/adopters mirrors ADOPTERS.md.

Addresses review feedback from @miguel-heygen on #876.
