fix: The version changelist table edit button opens all items outside of the sideframe

[Aiky30]

Description

An issue is present where all items in the Version Changelist table are opened outside of the sideframe when the edit icon is clicked. This should only be the case for PageContents and any other items with Placeholders that require a dedicated edit endpoint with a toolbar. All other items should continue to open in the sideframe.

Due to the nature of the check, the caching (cached property) prevents the calculation happening for every table row when rendering the Changelist, it is done once per model with VersioningItem configuration.
