providers/docker: Fix usability check
In commit 7980178d194bb21bde2e21858fbc969e4cc7eb3f (#10879) I added a
`usable?` class method to `VagrantPlugins::DockerProvider::Provider`.
However, commit 34e53a5a4b208edcc3e25c1f0e3aa0ef56e8d8d9 (#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.

Vagrant Core Plugins

These are plugins that ship with Vagrant. Vagrant core uses its own plugin system to power a lot of the core pieces that ship with Vagrant. Each plugin will have its own README which explains its specific role.
