feat(editor): Create separate components for JS and JSON editors (no-changelog) (#8156)

## Summary
This is part-1 of refactoring our code editors to extract different type
of editors into their own components.
In part-2 we'll
1. delete a of unused or duplicate code
2. switch to a `useEditor` composable to bring more UX consistency
across all the code editors.
