 * Added a new default option `asyncio_default_fixture_loop_scope = "function"` for `pytest-asyncio` as not providing a value is deprecated.
 * The migration script is now written in Python, so it should be (hopefully) more compatible with different OSes.
 * Disable more `pylint` checks that are also checked by `mypy` to avoid false positives.
+* Remove the redundant `--platform` from the testing dockerfile.
