Docs: Add note that export doesn't include volume data.
The documentation on `docker export` doesn't mention that
data in volumes is not included in the export.
This adds a note that volumes are not part of the export
and refers to the "Backup, restore, or migrate data volumes"
to give the user some pointers.
