There's this convention in linux CLI tools that if you're asking users for yes/no response, then you highlight the default choice with uppercase (e.g. [Y/n]) and let user stick with the default by just pressing Enter/Return.
This behavior is already present in bunch of places in ghcup installer. Could we please also support this in the prompts used by TUI?
