small clarification in the tutorial docs for cli arguments

[mina58]

In the optional cli arguments section, it said "To make a CLI argument optional, use typer.Argument() and pass a different "default" as the first parameter to typer.Argument(), for example None:" and the example was:

from typing import Optional

import typer
from typing_extensions import Annotated


def main(name: Annotated[Optional[str], typer.Argument()] = None):
    if name is None:
        print("Hello World!")
    else:
        print(f"Hello {name}")


if __name__ == "__main__":
    typer.run(main)

I thought it was confusing because when I read it for the first time i though i should write it like this

def main(name: Annotated[Optional[str], typer.Argument(default=None)]) -> None

which is wrong, so i clarified the text a little.

Hi, thanks for the PR!

This particular sentence in the documentation is already being addressed by #983, so I'll go ahead and close this one. Thanks again though!
