fix: also support passed ES Modules from css-loader in addition to CommonJS format

[foxxyz]

What kind of change does this PR introduce?
Fix for new default behavior of css-loader v4

Did you add tests for your changes?
No, due to small change and backwards compatibility. Happy to add if required.

Summary
Due to css-loader using ES Modules as the new default in v4, this module breaks when upgrading css-loader to latest (see #46, #42). This patch addresses that problem.

Does this PR introduce a breaking change?
No, tested to be backwards compatible.

Other information
Not sure what the future plans are for this module and whether it's still relevant when Vue 3 releases (I didn't see vue-style-loader listed as a dependency on vue3 bundles), so feel free to discard this patch if this module is to be phased out.

Fixes #46, Fixes #42

You're right, this is a much cleaner solution that addresses the problem at the root. Thank you @meowtec

Retested and verified.

Can we get this in?

Currently, guides/tutorials for ground-up Webpack setup using the latest css-loader are breaking without this, since late July.

Personally wasted a lot of time thinking it was a SSR issue. I imagine many beginners might have been deterred because they couldn't get past this styling bug.

Minimal bug reproduction here.

any good news?

This issue took me on my learning journey today 5+ hours before I found the relation to the css-loader version.. :/
