Remove pre-commit hook and add GHA dependabot config for managing hashicorp actions

Ref: https://github.com/hashicorp/terraform-providers-devex-internal/issues/174

(The pre-commit hook was really fighting my script and it doesn't seem necessary since we have CI already on PRs 🙂 )

I've come to doing the same locally regarding the pre-commit script, so 👍 from me there. We should take a look at the rest of the husky usage in this codebase and decide if its necessary.

I'll do that in a separate PR while it's fresh of mind 👍🏻
