Fix type annotation of typer.run

[yassu]

Problem: type annotation of typer.run is

def run(function: Callable[..., Any]) -> Any

However, this function returns None.

Solution: type annotation of typer.run changes to

def run(function: Callable[..., Any]) -> None

Alternatively, the last line of the function could be return app() instead of app(), but this probably isn't necessary.
