Support modifyOtherKeys to support shift+enter in tmux #15165
Description
What would you like to be added?
We should extend terminalCapablityManager to detect whether the terminal supports modifyOtherKeys
For terminals that do we should use it to detect shift+enter.
While tmux lacks support for the kitty protocol it supports the slightly older modifyOtherKeys protocol.
Why is this needed?
tmux users are unable to press shift+enter today. We are also missing out on differentiating ctrl-I and tab and similar cases.
