## Summary

This PR extends the string formatting to respect the configured quote style.

<!-- What's the purpose of the change? What does it do, and why? -->

## Test Plan

Extended the string test with new cases and set it up to run twice: Once with the `quote_style: Doube`, and once with `quote_style: Single` single and double quotes. 

<!-- How was it tested? -->
