Fixed error “Not registered handle” on admin grid

[Kashyap1999]

Description

Admin grid breaks and getting Error "Not registered handle" with the Exception. When we try to edit the page using page builder and try to insert image using html code, not registered handle Error will appear on display. This error also appears on custom grids. This Issue appears because the collection argument types are placed into area-specific file etc/adminhtml/di.xml, Magento used collection arguments at the global level etc/di.xml. The area-specific file overrides the global value. It can lead to problems for other grids.
