#6548 Fix autocomplete for offsetPlane (#6940)

* handle Plane in get_autocomplete_snippet to fix missing default plane value for offsetPlane

* adds test for offsetPlane default plane value

* cleanup test

* use XY instead of XZ for default plane

* add rust test for offsetplane autocomplete

* remove playwright test for offestPlane, as it has rust test now and there are autocomplete tests already
