SHIFT + ENTER should spawn a line break, but executes the prompt instead.

Describe the bug

SHIFT + ENTER is a standard/universal keystroke combo in most chat apps for spawning line breaks.

However, the Copilot CLI uses CTRL + ENTER to spawn line breaks, while SHIFT + ENTER (prematurely) executes the prompt.

Mildly annoying.

Affected version

GitHub Copilot CLI 0.0.410

Steps to reproduce the behavior

1. Type a small prompt in Copilot CLI.
2. Press SHIFT + ENTER.
3. The prompt is immediately executed.

Expected behavior

A line break would be introduced, and the cursor would go over to the new line.
