swagger-ui show request params as required even though they are Options

[eranrund]

Hello!

On commit 576f6c129010b4f6e6445c06393cfcf2cfee30df I am seeing the following struct:

#[derive(Clone, Debug, Default, Serialize, Deserialize, IntoParams)]
pub struct PageRequest {
    /// The maximum number of responses in a page
    /// Each route may have its own default if this is omitted
    #[serde(default)]
    #[param(required = false)]
    pub limit: Option<u64>,

    /// The page token, if the requester earlier got a paginated response.
    #[serde(default)]

    pub page_token: Option<String>,
}

Produce the following Swagger UI:

Specifying #[param(required = false)] has no effect either, both parameters still show up as required.

I am at a loss as to why this happens.

Thanks :)

Wrapping in #[into_params(parameter_in = Query)] as suggested in https://github.com/juhaku/utoipa/issues/622 seems to address this.
