Docker Image for Ubuntu 20.04 in the gem5 documentation is an incorrect version.

[Shreesh-Kulkarni]

The docker image for Ubuntu 20.04 in the documentation is an incorrect version. It redirects to 404 Page not found, and while pulling it via docker it says it doesn't exist. It should redirect to version 23:1 but the doc says its version 23:0. Documentation needs to update this.

Affects Ubuntu 20.04

Steps to reproduce the behavior. Please assume starting from a clean repository:

1. docker pull "ubuntu 20.04 image"
2. Error: image not found
