[Bug]: @query format does not accept deepObject

### Describe the bug

According to [this page](https://typespec.io/docs/getting-started/typespec-for-openapi-dev#openapi-v3) in the documentation the `format` parameter of `@query` decorator is mapped to the `style` field of OpenAPI parameters.

However, according to [this page](https://typespec.io/docs/libraries/http/reference/data-types#TypeSpec.Http.QueryOptions) `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

```tsp
model QueryParams {
@query(#{format: "deepObject"})
filter: Record;
}
```
