Fix Shift+Enter to send newline instead of carriage return in terminal (#33859)

Closes #33858

Changes Shift+Enter in the built-in terminal to send line feed (`\x0a`)
instead of carriage return (`\x0d`), enabling multi-line input in Claude
Code and other terminal applications.

Release Notes:

- Fixed the issue where Claude Code and other multi-line terminal
applications couldn't use Shift+Enter for newlines.
