Add linkchecker pre-commit hook configuration

[d33bs]

Summary

Thanks for the great effort on this project, it's been helpful!

This is a feature request to add a pre-commit hook configuration for linkchecker. Pre-commit provides the capability for custom hooks which may be used by others. Often, projects which provide the capability to perform checks will have a .pre-commit-hooks.yaml file. This provides a certain level of trust and development alignment (see Black's .pre-commit-hooks.yaml as an example).

Steps to develop and use

I think a .pre-commit-hooks.yaml file could be added with something like the following to enable this functionality:

- id: linkchecker
  name: linkchecker
  description: "Check for broken links in web sites."
  entry: linkchecker
  language: python
  # additional defaults?

Usage outside of this for others would entail configuring their .pre-commit-config.yaml with something like:

repos:
  - repo: https://github.com/linkchecker/linkchecker
    rev: vx.x.x
    hooks:
      - id: linkchecker
      # optional config below...
