Description of proposal (what needs changing)

The description of the visualizer plugin type might need to be clearer that it can only be used for 3D datasets.

From the docs:

• Visualizer: JS plugins can register a component that will override the builtin Sample visualizer

It may make someone think it can be used for any sample visualizer, e.g. the image visualizer. However, only Sample3D component checks for active plugins: https://github.com/voxel51/fiftyone/blob/61afb2df03996c9d23d91d469278c741179ba1e3/app/packages/core/src/components/Modal/Sample3d.tsx#L20
