Updated Weaviate Docker image url (auto PR by bot) (#320)

This minor change updates the URL of the [Weaviate Docker
image](https://weaviate.io/developers/weaviate/installation/docker-compose).

​Instead of the standard Docker registry, Weaviate now makes use of a
custom registry running at `cr.weaviate.io`.
