Provide option to add "Open in Windows Terminal (Admin)" to Explorer context menu

[TheAndyMac]

Description of the new feature/enhancement

As well as having the option to Open in Windows Terminal as a right-click in Explorer (which should be configurable as discussed in #9902 and #6113 ) it would be really helpful to have a configurable option to ALSO have an "Open in Windows Terminal (Admin)" option to quickly open up Windows Terminal with Admin rights to be able to access those commands which need it.

Proposed technical implementation details (optional)

Add an option in the configuration to enable/disable an "Open in Windows Terminal (Admin)" context menu option.

Yea, we'll make sure to include this in the configuration options. This is technically different than #6111 so I'll leave it open
