Use readline if available
Background
On POSIX systems, the use of input() at clean_input falls a bit short, since it does not allow for the use of arrow keys to correct mistakes, nor Emacs-like shortcuts that are generally used in the shell (Ctrl-A, Ctrl-E...).
Changes
On line 8 of utils.py, the module readline is imported if available. This is the case for all POSIX systems I know, but not for Windows. Importing readline sort of monkeypatches the input() global function to make it more user-friendly.
In the future, pyreadline could be considered as an alternative for Windows, but this PR disregards it.
Documentation
Even though I've added two lines, it seems appropriate to let the future readers know why that try-catch statement is there, so I've added a small comment.
Test Plan
- Run the current version of Auto-GPT and check that arrow keys do not work while inputting text; for instance, at the
Name your AI:prompt. - Implement the patch I've submitted, and run again on a POSIX system. Now, arrow keys and Emacs-like keybindings will work fine.
