add pre-commit config

[guykisel]

This PR is intended to implement #154 based on the docs at https://pre-commit.com/#new-hooks

It's not quite working but I think perhaps I am just missing something simple.

How I'm testing:

1. I've cloned https://github.com/sindresorhus/awesome locally.
2. I run pre-commit try-repo local\path\to\awesome-lint
3. pre-commit installs awesome-lint and runs it and fails with Invalid GitHub repo URL: local\path\to\awesome\readme.md

However, I can repro this same issue when just directly running awesome-lint locally on awesome:

PS local\path\to\awesome> npx awesome-lint
Need to install the following packages:
  awesome-lint@0.18.1
Ok to proceed? (y) y
✖ Invalid GitHub repo URL: local\path\to\awesome\readme.md

I think I'm hitting this bit of code: https://github.com/sindresorhus/awesome-lint/blob/main/index.js#L65-L68 - and it thinks my local path is a url? Might just be an issue with Windows or PowerShell. 🤔

Closing as this is not moving forward and it's not something I need or have time to dig into.
