f9047771d642c5887c752872b6ffbbd974603b35 lint: fix custom mypy cache dir setting (Fabian Jahr)

Pull request description:

  fixes #28183

  The custom cache dir for `mypy` can only be set via an environment variable, setting the `MYPY_CACHE_DIR` variable in the program is not sufficient. This error was introduced while translating the shell script to python.

  See also the mypy documentation: https://mypy.readthedocs.io/en/stable/config_file.html#confval-cache_dir
