[Feature] - Provide Demo Builds for Apple Silicon

[MariusBrill]

As for now we only provide demo builds for x86 architectures, which run very slowly on Apple Silicon devices. We should provide Docker Images for these architectures as well, tag them accordingly and provided the respective docker-compose files for Apple Silicon.

Meanwhile almost all images support amd64 & arm64 architectures.

Only the inspectit/spring-petclinic-* images have to be updated.
