Move installLocalDependencies and buildServer to Dockerfile

[copyrights]

Today the build pipeline consists of two steps. Prepare server build and build server locally and then build containers.

To ease local testing I like to suggest moving the server build into a FROM maven:3-eclipse-temurin-11-focal as kroki-build-server (or similar) section of the servers dockerfile.

And copy the jar from the builder

Why not, that's a good idea 👍🏻
