Ayaz Salikhov 9c92a2b51b style: Use pre-commit tool and add simple config (#2029) 
I started with really simple pre-commit hooks and will add more on top.

Important files:
- `.pre-commit-config.yaml` - the config for pre-commit
- `.github/workflows/pre-commit.yml` - runs pre-commit hooks in branches
and `develop`
- `.github/workflows/pre-commit-autoupdate.yml` - autoupdates pre-commit
hooks once in a month
