Update Dockerfiles and CI workflow to remove loading of Flux Spack environment. These containers are designed to run with Flux and Parsl so it makes sense to load the Spack flux environment at login rather than having to do it manually every time a command is run via docker exec or when logging into an interactive session in the frontend container.
In addition, creation of ssh keys is removed from the CI because the upstream base containers were updated such that the keys are already created. There is no longer a need to create ssh keys.
