Portal records are limited to 50 by default

Portal records are limited to 50 by default. We should be able to override this default limit by adding a property in PortalDataAttribute.cs

Here is how we can override this default limit -> https://community.claris.com/en/s/question/0D53w00005fqB3uCAE/50record-limit-on-portals-through-data-api

(Btw, we could also implement the offset portal property too).

I think we would need a more robust option than just a PortalDataAttribute button, because there still is no way to get the "next" page of data beyond that limit. By default its 50, meaning there is no way to get the 51st record; but if we make it configurable, and its configured to 500, there's still no way to get the 501st record.

I think the Find Request object needs some additional optional parameters which can be used to specifically paginate through portal data.
