Suggestion: [setup] Add an option to allow user to add "Open Cygwin Terminal Here" to Right-click menu

[Yang Yu Lin]

It would be convenient for users to open specific folder in terminal by just right-click it, like Git Bash and Windows Terminal.

Note: I hope this change would work on Windows 11 right-click menu. (Because I don't like "Show more options" or Shift + Right-click)
