ebdc17b8 - ENH: Enable readline support for transformers chat (#40911)

ENH: Enable readline support for transformers chat (#40911) ENH Enable readline support for chat This small change enables GNU readline support for the transformers chat command. This includes, among others: - advanced navigation and editing: ctrl + a ctrl + e alt + b alt + f ctrl + k alt + d etc. - navigate and search history: arrow up/down ctrl + p ctrl + n ctrl + r - undo: ctrl + _ - clear screen: ctrl + l Implementation Although it may look strange, just importing readline is enough to enable it in Python, see: https://docs.python.org/3/library/functions.html#input As readline is not available on some platforms (https://docs.python.org/3/library/readline.html), the import is guarded. Readline should work on Linux, MacOS, and with WSL, I'm not sure about Windows though. Ideally, someone can give it a try. It's possible that Windows users would have to install pyreadline (https://pypi.org/project/pyreadline3/).
