Move --break-system-packages settings to env variables

[mewim]

Description

We used --break-system-packages flags to work around PEP 668. However, this is not very robust. If the Python version is lower than expected, it will fail due to having an extra flag set. In this PR, we remove the flag and use env variables to pass it instead. The higher versions of Python should recognize the env and automaitcally set it for each pip install, while for lower versions this will be safely ignored.
