Add Ctrl+J for new line #660
Description
Describe the feature or problem you'd like to solve
I would like to use Ctrl+J for linefeed in terminal.
Proposed solution
I would be happy to see Copilot CLI can support this shortcut, so that I can input multiline prompt more conveniently.
(AFAIK I can only input new line with Shift+Enter OR \ Enter, as This Issue mentioned.)
