Example Code

import typer

app = typer.Typer(add_completion=False)

@app.command()
def hello(name: str):
    typer.echo(f"Hello {name}"

if __name__ == '__main__':
    app()

Description

When I use python myapp.py --help, the Rich panel appears, but I don't want it. I have already read the source code and I saw this:

typer/typer/main.py

Lines 39 to 47 in f83c66d

	try:
	import rich
	from rich.console import Console
	from rich.traceback import Traceback
	console_stderr = Console(stderr=True)
	except ImportError: # pragma: nocover
	rich = None # type: ignore

I have considered installing only typer without rich by using poetry add typer instead of poetry add typer[all]. However, since my project itself uses rich, it automatically detects it as a dependency.
So, I believe it would be more efficient to add a enable_rich parameter, like this:

import typer
app = typer.Typer(enable_rich=False)
...

Hello @anthonyraf, I made a pull request with an implementation of a feature similar to the one you described here.
Maybe you could write a review of my PR according to this ?
