⬇️(app-desk) downgrade @types/react-dom

Downgrade @types/react-dom to 18.2.18.
The lastest version seems to have lot of compatibility
issues with other packages:
- @openfun/cunningham-react
- @tanstack/react-query-devtools
- next

We add this package with this version to the ignore list
in renovate.json, when we will have a new compatible version, we will
remove it from the ignore list.
