no 'latest' tag on docker hub

[chessman]

I noticed that cschranz/gpu-jupyter doesn't have 'latest' tag anymore.

❯ docker pull cschranz/gpu-jupyter
Using default tag: latest
Error response from daemon: manifest for cschranz/gpu-jupyter:latest not found: manifest unknown: manifest unknown

Is it intentional? Doesn't it make sense to point to the latest image (v1.5_cuda-11.6_ubuntu-20.04 as of now).

Hi @chessman
GPU-Jupyter aims to create isolated environments for reproducible setups.
The latest tag contradicts this purpose, as it changes the setup version as soon as a later tag is pushed.
Even worse, as there are three branches slim, python-only and full, users wouldn't be aware which version they have and what packages should work!

Therefore, this purpose is intended, it nudges to use tags highly recommended for Docker anyways, even though a more precise feedback would be nice for those not familiar with Docker.
