docs: update quoting rules for PowerShell 7.3+ (#3649)

The manual recommended backslash-escaped double quotes inside the jq
program for all PowerShell versions, but since PowerShell 7.3 native
command arguments are passed with standard quoting by default, so the
backslashes reach jq literally.

Describe the quoting rules separately for Unix shells and PowerShell
7.3+, for older PowerShell and Windows PowerShell, and for cmd.exe, and
update the examples to match.
