Debug Sass import file abbreviations

[nicholaschiang]

Current workaround in src/subject-select/lib/subject-select.module.scss:

@use '@material/chips/_index.scss' as chips;

We want it to read like (this should automatically import _index.scss and create a chips namespace):

@use '@material/chips'

See this original issue for more info.

This might have something to do with the known issues with sass-loader's module resolution. See this issue for more info on that.
