Three more exception-related deprecations.

    * RefResolutionError is deprecated entirely.
      Use referencing.Registry-based APIs, and catch
      referencing.exceptions.Unresolvable if you really want to ignore
      referencing related issues.

    * FormatError should now be imported from jsonschema.exceptions
      only, not from the package root.

    * ErrorTree should now be imported from jsonschema.exceptions
      only, not from the package root.
