Add ruff for linting, remove flake8, remove isort, remove pylint

[gsheni]

• Added ruff for running linting
• Added ruff commands to Makefile
• Removed flake8 as dev dependency, since ruff does this, but faster
• Remove isort as dev dependency, since ruff has the same function, but faster
• Removed pylint as dev dependency, since ruff has more implemented rules
• Removed setup.cfg
