resolving #117

As per fastify/fastify#4264, swagger should support different content types responses.
Tests here will fail until the feature is merged at fastify, but I've hard-codded the fastify proposed changes and tested it.

You can change&push temporary the package.json to use your fastify branch:

    "dependencies": {
        "fastify": "github:iifawzi/fastify#supporting-different-content-types"
    }

so we will check the green ci

Suggested change

	Please use `content` for the response otherwise Fastify itself will fail to compile the schema:

I don't mind removing it though
