[BUGFIX] Handle smooth migration for renamed navigation ID

When migrating to TYPO3 v13, the navigation component
for rendering the page tree has been renamed with
https://review.typo3.org/c/Packages/TYPO3.CMS/+/81411

In TYPO3 v12:
- "@typo3/backend/page-tree/page-tree-element"

In TYPO3 v13.1:
- "@typo3/backend/tree/page-tree-element"

This change adds a proper deprecation message,
and a RST file for it.
