Refactor APIs to be a bit more explicit

Refactor example.

Thanks for proposing a different flavor of the API:

+1 for the additional headers, I think that it is a nice improvement let's have it in.
+1 for fixing the ingress port in the example
+1 for the dummyjson example, it is a nice demo.

Regarding the main API change, I'm on the fence but willing to roll with it :-)
So far in any project I've seen you'd usually get an argument object (strange but that is how it works 🤷‍♂️)
If you feel like this is more intuitive then +1 to merge this change.

I personally find this much more intuitive, and also in line with the RestateContext API. The object api is just counter-intuitive, and less explicit. Perhaps also @jackkleeman has an opinion about this?
