Use container precice/precice:develop in all Actions

[IshaanDesai]

This PR makes the develop branch of the bindings compatible with precice:develop.

Closes #161, closes #155

Because I would like to use the python bindings with my work in precice/precice#1523, I will work a bit on this branch today. Is there any additional (unpushed) work in this direction? I will start working on a private fork, but I can also push to this branch, if this does not interfere too much with your work (@Timo-Schrader and @IshaanDesai).

Sounds good, I don't have any other important changes currently.

Installation (pip3 install --user .) and tests (python3 setup.py test) work locally on my system if I use 8c52300. I think there are some problems at the moment (that we cannot really fix here):

• The Dockerimage precice/precice used by the tests is not pointing to develop, but to an older version with the outdated API. There is some work going on in this direction in Bring Repo to Working State setup-precice-action#1 and Setup-preCICE GitHub action precice#1544 in this direction.
• I have problems with the installation procedure of preCICE when using the current version of develop. See precice/SolverInterface.hpp and some more headers not found precice#1554 for details.

There are no unpushed changes from my side too. This is a pending todo in my list, and I am happy if you push this @BenjaminRodenberg :)

As far as I understand, the main problem why we cannot merge this PR is that the tests don't work with the new action precice-setup-action. Therefore, I removed this part of the testing procedure and instead use my own docker image benjaminrodenberg/precice:develop. See #169

We can still keep this PR and merge it as soon as the precice-setup-action is working. This would then upgrade the tests to this new workflow.
