Avro's parsing canonical form treats a primitive object schema like
`{"type":"string"}` as equivalent to the simple string form. Redpanda
previously kept the object form, so equivalent schemas could be stored
under different canonical definitions.
Keep the existing sanitize traversal unchanged. After sanitization, walk
only the parts of the Avro JSON that are schemas: record field types,
array items, map values, and union branches. This leaves
primitive-looking custom metadata as-is.
