FEniCS cases requirements.txt: fenics-dolfin not found

[MakisH]

Since #563, the FEniCS cases specify (for example, for the perpendicular-flap):

# Assuming FEniCS from ppa:fenics-packages/fenics was installed https://fenicsproject.org/download/archive/
# Use --system-site-packages in venv
fenics-dijitso==2019.2.0.dev0
fenics-dolfin==2019.2.0.13.dev0
fenics-ffc==2019.2.0.dev0
fenics-fiat==2019.2.0.dev0
fenics-ufl-legacy==2022.3.0

Trying to run the case (I admin I did not try that when I reviewed, as I wrote in the PR), I am getting:

Looking in indexes: https://pypi.org/simple, https://packagecloud.io/github/git-lfs/pypi/simple
ERROR: Could not find a version that satisfies the requirement fenics-dolfin==2019.2.0.13.dev0 (from versions: none)
ERROR: No matching distribution found for fenics-dolfin==2019.2.0.13.dev0

I recently ran the system tests a few times and this worked, though. It only recently started failing.

@NiklasVin @BenjaminRodenberg any clue what is going on here?

Looks like there was an update of some FEniCS packages recently. See https://launchpad.net/~fenics-packages/+archive/ubuntu/fenics.

I updated the package locally and now I have:

$ pip show fenics-dolfin
WARNING: Skipping /usr/lib/python3.12/dist-packages/pybind11-2.11.1.dist-info due to invalid metadata entry 'name'
Name: fenics-dolfin

Summary: DOLFIN Python interface

Previously, the version was 2019.2.0.13.dev0.

To make sure that this does not break again, I will use ~=2019.0 to specify any version compatible with 2019.0. PR comes in a moment.
