🛠 Fix tox configuration

[samet-akcay]

Description

• Current pre-commit and tox configuration sometimes cause discrepancies due to using different package versions of black, isort, flake8, pylint, mypy and pydocstyle. This PR addresses this issue by removing the individual checks from tox and running pre-commit run --all-files from tox itself.
