feat: rule now allows page[foo] defined without deepObject.

[philsturgeon]

Before it was demanding a deepObject, which not all tooling supports, and even when they do it somehow loses something.

Here is the deepObject rendered in Scalar.

I think I prefer this sort of view.

To do that (with the way existing tools work) it needs to be listed as two parameters.

components:
  parameters:
    PageNumber:
      name: page[number]
      in: query
      schema:
        type: integer
        minimum: 1
        default: 1

    PageSize:
      name: page[size]
      in: query
      schema:
        type: integer
        minimum: 1
        maximum: 100
        default: 15

So I've made the rule respect this sort of structure (without specifying exactly what page[foo] you use, as JSON:API does not either.
