Fix typo in schema

We should have been specifying a minimum number of properties for the
'mappings' field when creating allocations [1]. We were not, thanks to a
typo. Correct this typo.

+    Since microversion 1.34, it has been possible to provide a ``mappings``
+    field when creating new allocations via the ``POST /allocations`` or ``PUT
+    /allocations/{allocation_id}`` APIs. This field should be a a dictionary
+    associating request group suffixes with a list of UUIDs identifying the
+    resource providers that satisfied each group. Due to a typo, this was
+    allowing an empty object (``{}``). This is now corrected.
