Module-level aliases don't work

[GottemHams]

Bug report

Actual Behavior

Although this loader does support resolve.alias at the top level of the Webpack config, it seems module-specific aliases are ignored (module.rules[i].resolve.alias). This results in Can't find stylesheet to import errors, which occurs for both @use and @import. One reason for module-level aliases is so that every rule can have its own aliases, without any risk of accidentally importing SASS into TypeScript for example (or vice versa even).

ERROR in ./sass/entry.scss (./sass/entry.scss.webpack[javascript/auto]!=!./node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[0].use[1]!./node_modules/sass-loader/dist/cjs.js??ruleSet[1].rules[0].use[2]!./sass/entry.scss)
Module build failed (from ./node_modules/sass-loader/dist/cjs.js):

  ╷

  │         ^^^^^^^^^^^^^^^^^
  ╵
  sass/entry.scss 1:9  root stylesheet

This error seems to originate from sass-loader if I'm interpreting this correctly, which is why I created the issue here and not elsewhere.

Expected Behavior

Perhaps there is a way to just ask Webpack what aliases are relevant for the current loader/rule? That way it will keep working even if they ever add aliases at more levels.

How Do We Reproduce?

1. Clone the reproduction repo
2. Run npm i of course
3. Now you can do either npm run build-fail or npm run build-good

I only used @import in this example because it's closer to my actual scenario (can't use @use due to dependencies), and I figured it's pretty redundant to show @use since the behaviour is exactly the same anyway.

Please paste the results of npx webpack-cli info here, and mention other relevant information
