Expose new bundle entry at graph-app-kit/components

[oskarhane]

Allows for imports like:

import { Cypher } from ‘graph-app-kit/components.

I'll need to verify that unused code in that bundle are identified by webpack to reduce final app size.

We cannot bundle as umd to have webpack be able to tree shake. We must keep ES Modules for it to work.
