Use Ubuntu 24/noble as Docker base image

[holtgrewe]

Is your feature request related to a problem? Please describe.
We currently use Debian bookworm as the Docker base image. While this is nice and stable, we don't get modern rocksdb which we would need for the varfish-server-worker to use the system rocksdb library.

Describe the solution you'd like
Change the base image for the builder and runtime to be based on ubuntu noble. Synchronize this with updating the worker to use ubuntu noble as base image.

Describe alternatives you've considered
N/A
