Accept nullable parameter

[ronildosouzafb]

current behavior

schema = {
  "type": "object",
  "properties": {
      "github_url": { "type": "string", "nullable": true }
    }
}

# => The property '#/github_url' of type null did not match the following type: string
JSON::Validator.validate!(schema, { "github_url" => null })

expected behavior

schema = {
  "type": "object",
  "properties": {
      "github_url": { "type": "string", "nullable": true }
    }
}

# => true
JSON::Validator.validate!(schema, { "github_url" => null })

also, without nullable attribute

schema = {
  "type": "object",
  "properties": {
      "github_url": { "type": "string" }
    }
}

# => The property '#/github_url' of type null did not match the following type: string
JSON::Validator.validate!(schema, { "github_url" => null })
