Exercises do not work in the recommended docker image (conan too old, 1.28.1, but 1.32.0 required at least)

I practically cannot run the first example (_Exercise : Consume with CMake_ - https://academy.jfrog.com/path/conan/conan-essentials/583095) because the Conan version of the recommended docker is 1.28.1, but 1.32.0 is the minimum version required. I think it would be better to provide a docker image that works out of the box. Failing that, at least instructions on how to upgrade conan in our containers or steps how to lower the requirements.
