Json Schema Parsing Incorrect with empty objects (e.g. {})

[bbene]

When decoding, we are incorrectly using associative array stile which leads to issues with {} vs [] validation.

We should instead update this line to be:

$parsed = json_decode(json: $responseString, associative: false)

as well as update the exception handling appropriately.

This will likely cause breaking changes so will need a new major version number as well.

I'm not sure we have to change the decoded thing that is returned (that seems like a big mess even in our own repo) but we do have to validate either object-style or raw string version. Honestly it'd be pretty great if SchemaValidatorService had a version of validationResult that could act on an unparsed string.... even if it only looked like it took a string on the outside, and actually decoded it into object representation as its own private business, like the Opis example does https://opis.io/json-schema/2.x/quick-start.html

our \App\Http\Requests\Traits\ValidatesRequestBodyWithJsonSchema (which we should eventually share with the world also) actually decodes object style to validate, and array style to cast to a JsonModel:
