[feature] option to customize the prompt

[mindplay-dk]

Could we have an option to customize the cyan('?') here?

tuiuiu.js/src/prompts/index.ts

Line 150 in 9ca4051

output.write(`${MOVE_UP}${CLEAR_LINE}${cyan('?')} ${bold(message)} ${green(value)}\n`);

Looks like this was hard coded at 14 locations, so maybe this should be part of the theme?
