* chore(correlation): funnel story with correlation events and properties
This commit:
1. adds msw so we can easily mock the API requests
2. starts msw on storybook page load
3. adds the `mockServiceWorker.js` to storybook public folder so it can
be loaded by the frontend
4. adds a Funnel story that defines the funnel and correlation
responses
Note that we also define types for requests and responses. These could
be shared with the actual application code, so we can explicitly couple
the application changes to updating storybooks, i.e. to help avoid
stories going stale.
The requests and responses are quite basic, but they are sufficient to
be able to easily see and make changes. It has a requirement that it
should be easy for anyone else who comes to the code to easily parse and
be able to make updates. We don't want these to be rotten stories but
*the place* that people go to first when making their changes.
Having simple handwritten request/responses also introduces the
stability needed to, for example, use regression tests. Changes are
deliberate.
* refactor(storybook): move funnel stories to their own file
This also does quite a bit of cleaning up of the storybook and funnel
story code. Trying to come down on an acceptable way to manage the
sample data.
* dev(storybook): specify public dir when building storybook
I'm hoping this means that chromatic will function properly 🙏
* chore: add back the withApi decorator
* setup msw first
* dev(storybook): Make posthogjs work in chromatic
* dont use as cast for response types
* make hot module reload work
