"Create route prefix lists" returns response object in the wrong schema

[StrooprReply]

Describe the bug

When running the API call
https://api.strata.paloaltonetworks.com/config/network/v1/route-prefix-lists
to create a prefix list the response object ist returned in the wrong schema.
The type.ipv4.ipv4_entry[x].prefix object is returned as type "list" instead of type "dict" (which would include either "network" or "entry" as following object).

Example:
{'ipv4': {'ipv4_entry': [{'action': 'permit', 'name': 5, 'prefix': [{'greater_than_or_equal': 16, 'network': '10.64.0.0/16'}]}]}}

The object is still created fine in the SCM.

Expected behavior

The type.ipv4.ipv4_entry[x].prefix object should be returned as type "dict" (which would include either "network" or "entry" as following object).

Current behavior

The type.ipv4.ipv4_entry[x].prefix object is returned as type "list" instead of type "dict" (which would include either "network" or "entry" as following object).

Possible solution

Steps to reproduce

1. create a route prefix list
2. observe response object
