PowerShell completion reports When parameter for Document keyword

[BernieWhite]

Description of the issue

Completion reports -When is valid for the Document keyword. This is incorrect and should be -With instead.

This is only an issue for command completion within VSCode. This doesn't affect execution which correctly uses -With.

Expected behaviour

Update parameters for document keyword.
