fix: enhance pre-commit configuration to prevent test_formatting.tf file issues

- Add comprehensive exclude patterns to prevent temporary test files from being processed
- Add explicit exclusions to all terraform hooks (fmt, validate, docs, tflint)
- This should resolve the ''Invalid single-argument block definition'' errors in CI
- Addresses malformed test_formatting.tf file creation during pre-commit execution
