feature: add musllinux_1_2 support (#1561)

* feature: add musllinux_1_2 support

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* fix[test]: clean-up docker images in test_*linux*_only.py

We are reaching disk space limits (14 GB) when running tests.
Add a fixture to clean-up docker images after tests.
This fixture is applied on tests that pull a specific image for one test only in order not to take too much time pulling that image many times.
