ER: Refactor Sass/ .scss to latest version after Homepage Launch

### Dependencies
- [ ] After Homepage Launch
- [ ] Following the lead of the [Internship Design System](https://github.com/hackforla/internship-website-design-system)

### Emergent Requirement - Problem
Our repo appears to be using an older version of Sass. Updating to the more modern syntax might be a large undertaking that we should do eventually by following the lead from the Internship Design System, but not till after the Homepage Launch.

At the dev meeting 5/20/24, we discussed that as a short-term fix we would revert the `github/super-linter@4.8.1` and decline future Dependabot updates temporarily.

### Issue you discovered this emergent requirement in
- #5048

- [X] YES
- [ ] NO

### Who was involved
@ExperimentsInHonesty @JessicaLucindaCheng @roslynwythe @marioantonini @t-will-gillis

### What happens if this is not addressed

### Resources

### Recommended Action Items

### Potential solutions [draft]
- In the short term, revert to `github/super-linter@4.8.1` and decline future Dependabot updates.
- In the long term, follow the lead of the Internship Design System ( after the Homepage Launch ) to refactor our .scss files as needed and decide whether to continue with the super-linter.
- If we continue with super-linter, restart the Dependabot updates - by reopening #6713 (?)
- Once we know how we want proceed we can formulate a plan to address this.
