Bug report: omitted array parameters with `array_use_braces: true`

When array_use_braces is set to true, array parameters are omitted when they are body parameters but don't explicitly specify documentation: { param_type: "body" }.

Example:

# with add_swagger_documentation(array_use_braces: true)

params do
  requires :param1, type: Array[String]
  requires :param2, type: Array[Integer], documentation: { param_type: "body" }
end
post :foo do
  { declared_params: declared(params)
end

The spec will look like:

"postFoo": {
  "required": ["param2"],
  "type": "object",
  "properties": {
    "param2": {
      "type": "array",
      "items": { "type": "integer", "format": "int32" }
    }
  }
}

It is particularly annoying if one wants to share some params between GET and POST/PUT/PATCH endpoints and rely on the implicit behavior to have the params be query params or body params as appropriate.

Reproduce the example using add_swagger_documentation(array_use_braces: true) with the shared params and compare the generated specification. Trace how the array parameters are classified for GET versus POST/PUT/PATCH body parameters; done means the implicitly body-scoped param1 is included while the explicitly documented param2 remains correct.
