Python 3.6 is EOL for years

[smartsammler]

In the Dockerfile on the master branch, you are still using Python 3.6 which doesn't receive security patches for almost three years and no features for almost six years.
Is it easily possible to run it with a current Python (atm 3.13) by just replacing the version numbers in the Dockerfile?

IMHO it would make sense to provide a Dockerfile with a recent Python version, because it is used in the dockerized version which is recommended in the deployment guide.
