Description of your changes

This PR adds support for __GIT_WORKING_DIR__ to the new terraform_checkov hook.

Since the new hook cd into each directory, it now ignores the checkov.yml file in the root folder. The functionality can now be restored with:

- id: terraform_checkov
  args:
    - --args=--config-file __GIT_WORKING_DIR__/.checkov.yml

How can we test changes

1. Create a checkov.yml in the top directory
2. Commit something that will trigger terraform_checkov in a subdirectory:
   • the config file is ignored
3. Add --args=--config-file __GIT_WORKING_DIR__/.checkov.yml to the .pre-commit-config.yaml file
4. Commit something that will trigger terraform_checkov in a subdirectory
   • the config file is now taken into account

Please, add related documentation to the readme (You can copy-paste related to __GIT_WORKING_DIR__ doc from tfsec and little-bit change it)

Let's maintain one style across the codebase. Also, no need to expand ARGS to an array
