Fix Context Menu Items

The context menu options "Open Terminal Here", "Center Map Here", "Add to Do Not Scan List", and "Copy to clipboard" do not work properly in Version 23.04.0; this MR fixes this problem.

P.S. I am unsure about the intended purpose of "Center Map Here" option, therefore I've kept the original lines as commented out and made the option operate as if the folder was left-clicked.
