Error when Foxx is disabled on the server

[grahamlyons]

If Foxx is disabled on the ArangoDB server then the reload() method on the Foxx class will raise an error:

requests.exceptions.HTTPError: 501 Server Error: Not Implemented for url: https://arango:8529/_db/example/_api/foxx?excludeSystem=False

https://docs.arangodb.com/3.12/components/arangodb-server/options/#--foxxenable

Python: 3.12.4
pyArango: 2.0.2
