feat: record non-onboarding product intents for data warehouse

[raquelmsmith]

Problem

Data warehouse isn't a product we expect most people to start with. So, we should evaluate if interested people are getting set up with it properly using some other starting point.

Changes

Record a product intent when someone clicks the Link button on a source.

@PostHog/team-data-warehouse is this something you think reasonably shows interest in the product aside from just clicking around? We can also record it after someone clicks a couple times, or does some other action.

👉 Stay up-to-date with PostHog coding conventions for a smoother review.

Does this work well for both Cloud and self-hosted?

How did you test this code?

Need to update tests.
