I updated react-dev-utils/getCSSModuleLocalIdent to make the cases of index.module.scss and index.module.sass consistent with its behavior for index.module.css, meaning that all three should (approximately) output [folder]_[localName]__[hash] as their localIdent.
I also added tests to ensure this works correctly, but sadly I couldn't run them on my machine so I'll piggyback your CI.
