Missing the value of 'deprecated' field

[ackintosh]

Example json in OAS v2:

{
    "swagger": "2.0",
    "info": {
        "version": "1.0",
        "title": "x-example"
    },
    "host": "httpbin.org",
    "basePath": "/anything",
    "schemes": [
        "http"
    ],
    "paths": {
        "/{foo}": {
            "get": {
                "responses": {
                    "200": {
                        "description": "OK"
                    }
                },
                "deprecated": false
            }
        }
    }
}

In case of deprecated: false like above or the field is omitted, Operation.getDeprecated() returns null.
I think Operation.getDeprecated() should return false in that case. There is the same issue in OAS v3.

I'll submit a PR that fixes this issue.
