Subject: [PATCH] test: use Petstore spec from GitHub

We're seeing intermittent issues from the Petstore project such as:

    error loading swagger spec in spec.yaml
    : failed to load OpenAPI specification: error resolving reference
    "https://petstore3.swagger.io/api/v3/openapi.json#/components/schemas/Pet":
    error loading "https://petstore3.swagger.io/api/v3/openapi.json":
    request returned status code 403

We can try and switch to the raw spec in GitHub to do this lookup, to
avoid hitting the Petstore API.

It's unclear if GitHub are going to be more performant, but it may help.
