Support args for terraform-fmt, remove hardcoded args.

**Describe the solution you'd like**
I want to be able to pass my own args into `terraform fmt`. Right now, it will only check and error out instead of allowing us to autofix on pre-commit.

**Describe alternatives you've considered**
The alternative is what it is now, which doesn't support autofixing

**Additional context**
I stopped using this pre-commit in favor of terraform-fmt pre-commits that allow for `--write=true` arg injection.
