Fix multiple uploaded files examples

[t0yohei]

Adjust the multiple example parameters.

I get this linting error with an endpoint that receives an uploaded file: unknown tag !<!ruby/object:File>

The spec is structured in this way:

  describe "POST /api/v1/my_pages" do
    subject do
      post api_v1_my_pages_path(my_page), params: params, headers: default_headers
    end

    let!(:user) { create(:user) }
    let!(:my_page) { create(:my_page) }
    let(:params) { { example: { title: 'test', images: [fixture_file_upload('/images/Logo.png')] } } }

      it 'success' do
        sign_in user
        expect(response).to have_http_status(:created)
      end

I have added the fix for this issue by speculating that the cause lies in the schema_builder.rb file's failure to handle cases where image is sent as an array.
