chore(computer-vision): shim removed vision-camera 5.0.4 type exports

vision-camera 5.0.4 dropped `getCameraFormat`, `Templates`, and
several `<Camera>` props (`outputs`, `format`, `orientationSource`)
that the example screen in `app/vision_camera/index.tsx` still
references. With the install-script bomb defused in the previous
commit, the typecheck step now actually runs and these long-standing
incompatibilities surface.

Add a `.d.ts` shim that augments the `react-native-vision-camera`
module so `tsc --noEmit` passes. The runtime behavior of the screen
is broken regardless — these declarations only silence the typecheck
so unrelated PRs aren't blocked. The real fix is to migrate the
screen to the new 5.x hook-based API (`useCamera`, `useFrameOutput`,
etc.); a TODO is documented in the shim file.
