Summary

🤖 Generated by Copilot at 15e1e2a

This pull request improves the support for style modules and assets in webpack by adding new resolution properties and updating the test cases. It modifies the lib/config/defaults.js file to define and apply the new properties, and the test/configCases/css/css-import files to import and test different style modules.

• Add styleResolutionDefaults object to define common properties for resolving style modules (link)
• Test the cascading effect of css imports by importing style-import.css in style.css (link)

I'll let you use best judgement here, I think the key detail to document with this feature is that using experiments.css means that styles will be added as a resolvable main field.

If possible it would be fantastic to leverage the test case examples to call out examples in the docs. <3 @burhanuday I'd appreciate if you could assist if @chenxsan or another contributor needs assistance.

I'll take up the documentation effort for this
