Add support for symbolized keys

[mbykovskyy]

Currently, parsed JSON with symbolized key fails validation. Please add support for validating JSON with symbolized keys.

Have you got an example for what this trips up on?

For example, Using activerecord_json_validator and passing a schema with symbolized keys like this : validates :data, presence: false, json: { message: ->(errors) { errors }, schema: { type: :object } } Raise this error : JSONSchemer::InvalidSymbolKey (schemas must use string keys)

But like this validates :data, presence: false, json: { message: ->(errors) { errors }, schema: { "type" => :object } } Works fine

Released in 2.0.0. Schema keys are deep-stringified to support symbols.

Note: symbol values are not supported (eg, type: :object above).
