Update pre-commit configuration to use prek

- Remove custom git hooks and related scripts.
- Create `.pre-commit-config.yaml` with standard hooks and `black`.
- Update `Makefile` to use `prek` for checking and installing hooks.
- Replace `linter_require_black.yaml` workflow with `prek.yaml`.
- Update `README.md` with instructions for `prek`.
- Ensure `git config core.hooksPath` is unset during hook installation.
