Add workspace .ansible directory to default exclude

Since we use it for collections and roles and it is probably not already added to the users gitignore, should we addit as a default?

(It should probably be in the gitignore but in case it isn't)

I have nothing against it but there is one small note: if someone is cloning their collection or role directly inside ~/.ansible/... and they try to lint it or use molecule, a default exclude path like this might prevent them from finding anything. If we do it, we need to be sure this would happen.
