No support for query parameter `published_at_gt` and others

[frastel]

We are in the need to filter stories according their published date. The "published_at" field is a native field in Storyblok and thus not filterable by gt_date or lt_date operations.

Expected Behavior

It is possible to use these query parameters from the Storyblok API:

• published_at_gt
• published_at_lt
• first_published_at_gt
• first_published_at_lt
• updated_at_gt
• updated_at_lt

Current Behavior

The possible query parameters are currently hardcoded in the StoriesRequest. It is not possible to bypass any other parameter which the Storyblok API supports.
See also #34.

Current workaround: No workaround possible as StoriesRequest is declared as final and thus we have no way to modify this class on our own. We can't use the SDK due to this problem for now. For any other issues we have found workarounds.

Steps to Reproduce

Try to filter stories according their published date with the SDK.

I am currently working on this issue as it blocks us currently.

I would introduce a "QueryParameterCollection" (suggestions for better naming is welcomed) and add it to StoriesRequest. All mentioned dates are possible to be added there.

Hey @frastel do you have a link to the docs where this functionality is described?

[frastel]

Sure, https://www.storyblok.com/docs/api/content-delivery/v2/stories/retrieve-multiple-stories.

I have also the confirmation from the Storyblok support, that published_at or updated_at could not be filtered by gt_date or lt_date operations.
