Fix TypeVar for decorators that handle Commands
The old type var would throw away the types of Callables.
```
import click
@click.option("--name", prompt="Your name", help="The person to greet.")
def hello(name: str) -> None:
...
reveal_type(hello) # note: Revealed type is 'def (*Any, **Any) -> Any'
```
With this small adjustment mypy now knows that it's a `'def (name: builtins.str)'`
