feat: Add document method accepting ResourceSnippetParametersBuilder

[Arachneee]

I'm using your library well.

It's possible to write like the code below, but there's a bug where responsefields and requestfields are initialized. So I added document parameters.

There will be no problem in the process of introducing the restdocs-api-spec library to restdoc, but if you write it with the restdocs-api-spec library from the beginning, it is very useful to write it as follows.

resultActions
                .andExpect(status().isOk())
                .andDo(document("cart-get",
                                new ResourceSnippetParametersBuilder()
                                        .tag("cart")
                                        .description("Get a cart by id")
                                        .responseSchema(Schema.schema("ResponseCart"))
                                        .pathParameters(
                                                parameterWithName("id").description("the cart id"))
                                        .responseFields(
                                                fieldWithPath("total").description("Total amount of the cart."),
                                                fieldWithPath("products").description("The product line item of the cart."),
                                                subsectionWithPath("products[]._links.product").description("Link to the product."),
                                                fieldWithPath("products[].quantity").description("The quantity of the line item."),
                                                subsectionWithPath("products[].product").description("The product the line item relates to."),
                                                subsectionWithPath("_links").description("Links section."))
                                        .links(
                                                linkWithRel("self").ignored(),
                                                linkWithRel("order").description("Link to order the cart."))
                        )
                );
