An obsolete reference in Studio to an editor toolbar element was removed because that element no longer exists. This keeps Studio aligned with the updated editor and helps avoid maintenance issues without changing user-facing functionality.

This PR removes a mention to `#table` div of `web_editor.toolbar`, as it is being removed by the commit in community version.
