Can't wait for the finished product.

Would like to compare it to patchlevel/event-sourcing (I am using currently). Which is a very simplistic way of using event-sourcing. (Also has some symfony integration)

Includes: * tests * example domain and docs for it * full static analysis pass * good coverage Required adding some more dependencies: * `symfony/console` (used in `doctrine/migrations` underlying components) * `php-standard-library/psalm-plugin` for better type inference As this stands, this still needs to go through CS checks, but that will happen in a separate commit, to avoid breaking the current achieved stability.

The idea is that the same `Dockerfile` used for CI can be used for running the workshop, so we roll with that. That means a less nice CI pipeline, but good enough for our purposes. Note how CI does **NOT** push the docker image: since this is a public repository, we cannot really perform docker registry pushes consistently, since the pipeline would always fail due to missing secrets. Also, we had to revert the SQLite JSON access syntax: not yet available for PHP + Ubuntu 22.04.
