Update pre-commit hooks

• Bump all hooks to the latest versions using pre-commit autoupdate command. As a result, unsuccessful pre-commit jobs in GitLab CI caused by the outdated isort version are resolved.
• Closes #45

@ToucheSir Haven't tested it out on existing projects. I recently started using the cookiecutter for python projects and came across failed CI jobs due to either the broken flake8 hook or the outdated isort version so I updated the hooks and that fixed the issues.

However, I did a quick test locally with .py, .R and .ipynb file, it was working as expected.

Great, I think this is good to go then.
