Support actix_web::Result for Query Parameters

[Martichou]

Hey there! First of, thanks for this library, it's pretty useful :)

So my use case is as follow:

/// Get events time series analytics.
///
/// This endpoint returns click and scan counts over time.
#[protect("_USER", "owner")]
#[api_operation(tag = "analytics")]
pub async fn get_events_timeseries(
    Header(CurrentOrg(current_org)): Header<CurrentOrg>,
    pool: web::Data<PgPool>,
    _key: ApiKey,
    query: actix_web::Result<web::Query<AnalyticsTimeRange>>,
) -> Result<OkJson<Vec<TimeSeriesStats>>, errors::PError> {
    ...
}

Currently, apistos doesn't document the query parts as parameters in the openapi spec generated, it's omitting it. I suppose this is because actix_web::Result isn't supported (can it even be supported?).

I see the same issue when using Option<>, it's just omitted instead of marked as non-required.

If you have some time to look at it, or even just to point me on how it should be resolved (if possible), it'd be appreciated!
