Add 'console' Attribute Support in 'launch.json' for Terminal UI Debugging

[azazar]

Perl-LanguageServer doesn't support "console" in "launch.json", hindering debugging and running of terminal UI apps.

Did you see #149 ?
And #166 ?

This may help you, if you need just stdin redirection.
But may not, if you want to debug a real console UI

I would expect the handling of different consoles is implemented by vscode itself. If this is not the case, I am not aware how to do this. Any hints or even better, a push request, are welcome.
