the "--no-additional-properties" flag is not working

[frosato-dev]

It looks like the --no-additional-properties flag is not working as expected.

Expected result: It should raise an error if an attribute is present in an example but not declared in schema.

Actual result: No errors were found. The given example is considered valid.

To reproduce the issue:

test-with-extra-property.json

{ "id": 123, "name": "Bob", "gender": "male" }

openapi-spec.yml

swagger: "2.0"
info:
version: 1.0.0
consumes:
- application/json
produces:
- application/json
paths:
/user:
get:
responses:
"200":
schema:
type: object
properties:
name:
type: string
id:
type: integer
required:
- name
- id

command ran

yarn openapi-examples-validator \
--schema-jsonpath $.paths./user.get.responses.200.schema \
--example-filepath ./test-with-extra-property.json \
--no-additional-properties \
./openapi-spec.yml

console output

Validating single external example
Schemas with examples found: 1
Examples without schema found: 0
Total examples found: 1

No errors found.

I would have expected the `gender` attribute to raise an error because it's not part of the API spec definition.

Let me know if you need more info or if I can help.
