Subject: [PATCH] Add optional --quiet arg to trailing_whitespace

Allows `trailing_whitespace` to simply run without creating a failure.
example:
```
repos:
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v4.4.0
    hooks:
      - id: trailing-whitespace
        args: [--quiet]
```
