[victor-teles]

Summary

This PR fixes #300

About the resolution

After some research in prettier repo, I discovered that regex expressions should only be considered simple if they have a length less than or equal to 5

Prettier ref: https://github.com/prettier/prettier/blob/d4d4b185e0ddc3e0dd839b873e2ee7fe8131b684/src/language-js/utils/index.js#L761C1-L761C1

Test Plan

• Validate snapshot 😄
• Added some regex cases
