chore: Plugin Action Editor routing (#37389)

## Description

- Earlier we had the new Plugin Action Editor implementation mixed in
with the older API and Query Editor components. We have now separated it
out so that the eventual removal of older editors is easy
- Move AppPluginActionEditor outside the EE split
