Pre-commit hooks don't include scss_lint with same parameters

[pt2302]

Expected Behavior

The pre-commit hooks should catch linting errors with scss, by also running scss_lint with the same parameters as when running npm run scss_lint.

Current Behavior

Pre-commit is not catching all linting errors, but tests will fail when pushed to GitHub.

Steps to Reproduce

Introduce the error Expected empty line before rule rule-empty-line-before into a modified .scss file. Pre-commit will still pass.
