Support external terminal option

Is your feature request related to a problem? Please describe.

The issue

I was trying to find a way to run the debug session whitin an external terminal (such as Warp / iTerm2) - based on the default terminal setting, for MacOS it is terminal.external.osxExec.

Describe the feature you'd like

My suggestion

A nice checkbox for enabling this feature, so once I'm hitting on the new debug session (by the code lens on the package.json OR with any menu exists, such as the NPM SCRIPTS) - the new debug session would trigger commands over my default terminal.
