Anders Kaseorg 5b4dcf9443 providers/docker: Fix usability check ... In commit 7980178d19 (#10879) I added a `usable?` class method to `VagrantPlugins::DockerProvider::Provider`. However, commit 34e53a5a4b (#10890) incorrectly changed it to an instance method. This rendered it ineffective because it’s called on the class, not an instance. Change it back to a class method.
