Hotfix/1.2.3: New docker base image

[nsoblath]

The base image is now p8compute_dependencies:v1.0.0, which is based on Ubuntu 20.04 instead of CentOS.

Testing the build locally worked for me.

The docker image built for me, but when I tried to execute source $MERMITHID_BUILD_PREFIX/setup.sh inside the container, I got an error: bash: python: command not found.
Perhaps that is because it needs python3?

[nsoblath]

@taliaweiss I think you're right. I changed the use of python in the setup script to python3, and it worked in the test I just ran.

[taliaweiss]

Thank you for making that change – sourcing the setup.sh file now works well!

However, when I try to run a termite script (fake_data_stan_analysis.py) in the container, I get the error included below.

I think this is what's happening: morphoorg/morpho#151

I get the same error as Talia. Is it possible that PyROOT is still build for python 2 instead of 3?
During building I get several warnings from morpho. Do we have to make the python and/or pip version change in morpho too?
