Unity logs "Mirror.NetworkInformationPreview was not disposed properly. Make sure that base.Cleanup is called" because ObjectPreview subclasses must call base.Cleanup() when disabled.

• Add OnDisable() => base.Cleanup() to NetworkInformationPreview

The CI failure was because ObjectPreview.Cleanup() doesn't exist in Unity 2020.3. Wrapped the call with #if UNITY_2021_3_OR_NEWER to fix it.
