Add Ctrl+J for new line

[cppHusky]

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.)

Example prompts or workflows
