Bump clang-format requirement from v12 to v20 (#1321)

The version in .pre-commit-config.yaml isn't bumped from v12.0.1 to v20.1.0
here as the GitHub Actions workflow triggers for it differ:

- pre-commit fires on `pull_request` and `push`, so needs to be changed at
  the same time as the formating changes
- `PR_clang-format_test` fires on `pull_request_target`, so needs to be
  merged before the formatting changes
