See wp-cli/wp-cli#5480.

This removes the script which sets up the pre-commit hook and its corresponding script. Unlike in wp-cli/wp-cli#5868 here is nothing to remove from composer.json, which means these scripts are not in use anyway.

If you have this pre-commit script installed, you can remove it by deleting the .git/hooks/pre-commit file.

Steps for testing

1. Clone this repo
2. Run composer install
3. Confirm no pre-commit hook has been installed into .git/hooks/pre-commit
4. Commit some code that would normally fail coding standards checks
5. Confirm there's no error message and the commit succeeds
