[11.x] Add AsCommand attribute to Console commands stub by default

[wilsenhc]

Just thinking that maybe this should be the default behavior after all the work done in #50617 so I updated the stub.

Or maybe it would be better to setup a new Laravel contract/attribute that inherits from Symfony's AsCommand and maybe clean up some stuff from the Commands structure as to not have duplicate values everywhere? And target this change for 12.x instead

Like moving the signature, description and aliases to be by default in the AsCommand attribute (with fallback to the class attributes for backwards compatibility)

Let me know what you think!

I think it's generally fine to not have this. We mainly did it in the framework because we have so many commands.
