improvment: change alt+enter multiline key with shift+enter

[nicoovh]

alt+enter is sometime taken by desktop application,
could it be changed to shift+enter instead (like webex),
or configurable?

I tried editing the following line to take ctrl into account, but without success:

shai/shai-cli/src/tui/input.rs

Line 275 in fc02a60

if key_event.modifiers.contains(KeyModifiers::ALT) {

Wondering whether there's something to do with the shell as well. I'm using fish, and after disabling Wezterm binding for Alt+Enter fish, Alt+Enter inputs a new line in the shell.
