Support @apiResource with missing @apiResourceModel

[ccec1t91077]

Update：

• Allow generate document without @apiResourceModel tag (but will remind you didn't use the @apiResourceModel tag)

This is a little feature to allow the document generate when the JsonResource is working with empty resource which means won't have any model to specify on the @apiResourceModel tag.

This might help some project using JsonResource to manage the api response which like webhook api or none data response api.

From #652.

Can you add a test for the expected behaviour? You can look at the existing ApiResourceTests for an example.

Hi, I've added tests but I'm not sure if I'm doing things correctly, because I don't have much experience for writing tests, so if I did something bad please correct me, ty. 🙂
