Use posthog js v2

[pradel]

Looks like posthog released a V2 of their package, would be great for this package to support the latest version! https://github.com/PostHog/posthog-js-lite/tree/master/posthog-node

The first step is probably to change to this: https://github.com/PostHog/posthog-js-lite/tree/master/posthog-node

Due to this: https://github.com/PostHog/posthog-node

This is probably something we want in general to remove the posthog-node.d.ts file.

Are you up to the task, @pradel? 🚀

@simenandre we are removing nest.js from our app and don't use the package anymore 😢 Thanks for creating this package!
