AutoGPT fix: use a modern prompt to avoid ^[[D char when using arrow left and…

Background

This PR aims to fix an issue with the input prompt where arrow keys would generate unwanted characters (^[[D) in the input when using arrows.

We also want to ensure that the colored output works correctly with the new input method.

prompt_toolkit also support history with up and down arrow which could be useful if we plan to have more user interaction with the agent in the futur

Changes

Replaced the input() function with prompt_toolkit's PromptSession to prevent unwanted characters when using arrow keys.
Adjusted all clean_input calls to use prompt_toolkit's HTML formatting instead of colorama ANSI escape codes.
Added the prompt_toolkit package to the requirements.txt file.

Documentation

The changes are documented in the form of in-code comments and by updating the clean_input function to accept FormattedText from prompt_toolkit.

Test Plan

Tested the changes by running the script and interacting with the modified prompts. Verified that the arrow keys no longer produce unwanted characters and that the colored output is displayed correctly.

There is an another PR regarding this with readline. Why this is better than that?

Check #2558

Hi @hdkiller

realine is already a good improvement but i believe that we will have much more interaction with auto-GPT using the terminal in the futur and readline is really basic.

prompt_toolkit allows:

multi-line editing
syntax highlighting
input validation (which can be really neat using gtp 3.5 turbo)
auto-completion
creating complex user interfaces with colors, styles and widget like progress bars, menus, dialog box, html tags ect..
mouse interaction

Which i believe will make the terminal UX much better.

I kept this PR small to know if you guys are willing to use prompt_toolkit. But i can create an other PR if this one is merged to show case how we can improve the current UI.

Some cool improvement could be to have options when auto-GPT want to execute a task, for example you want to do a web search Auto Gpt prompt display 3 option (BIng / google / duckduck go), you could use the arrow to choose between those 3 choices.

I think it will push the terminal interaction to an other level

FYI: early experiments using prompt-toolkit (the idea was to easily reuse/edit previous commands again, and to have autocomplete for directories and file names inside the workspace): #4078
