Non-interactive mode for --shell and integration changes (#455)

* Added --interaction that works with --shell option.
* Changed shell integrations to use new --no-interaction option.
* Moved shell integrations into dedicated file integration.py.
* Changed --install-integration logic to install integrations without downloading sh scripts.
* Removed validation for PROMPT argument, empty string by default.
* Fixing an issue when sgpt is being called from non-interactive shell environments.
* Fixed and optimised Dockerfile.
* README.md improvements, and new feature examples.
* New funny demo video.

 # ShellGPT
 A command-line productivity tool powered by AI large language models (LLM). This command-line tool offers streamlined generation of **shell commands, code snippets, documentation**, eliminating the need for external resources (like Google search). Supports Linux, macOS, Windows and compatible with all major Shells like PowerShell, CMD, Bash, Zsh, etc.

+If you would like to pass generated shell command using pipe, you can use `--no-interaction` option. This will disable interactive mode and will print generated command to stdout. In this example we are using `pbcopy` to copy generated command to clipboard:

 ### Shell integration
-Shell integration enables the use of ShellGPT with hotkeys in your terminal, supported by both Bash and ZSH shells. This feature puts `sgpt` completions directly into terminal buffer (input line), allowing for immediate editing of suggested commands.
