[Bug]: @query format does not accept deepObject

[sagikazarmark]

Describe the bug

According to this page in the documentation the format parameter of @query decorator is mapped to the style field of OpenAPI parameters.

However, according to this page deepObject is not a valid value (which kinda makes sense, since it's OpenAPI specific)

I coudln't find any other way to set style on an OpenAPI parameter.

Reproduction

model QueryParams {
    @query(#{format: "deepObject"})
    filter: Record<string>;
}

I stumbled upon this problem today. It was indeed quite confusing. There's a docstring in the repository:

typespec/packages/openapi3/src/examples.ts

Line 366 in 924435b

| query | form | form, spaceDelimited, pipeDelimited, deepObject |

that mentions that deepObject is supported for query, however there's no way to set it. the deepObject itself can also be found in here: https://typespec.io/docs/emitters/openapi3/reference/js-api/type-aliases/openapi3encoding/#_top however it wasn't obvious to me how can I use this.
