CSS sourcemap generation causing issue with JS sourcemap generation

[kp-entrust]

Description
Vite currently supports CSS sourcemap only on dev, not on build. It also supports JS sourcemap on both environments. When this plugin is installed in a Vite codebase, the build process is unable generate the CSS sourcemap. This issue also causes the JS sourcemap from being generated fully.

Error
"Sourcemap is likely to be incorrect: a plugin (inline-css-modules) was used to transform files, but didn't generate a sourcemap for the transformation. Consult the plugin documentation for help"

Versions:
vite 3.0.0
vite-plugin-inline-css-modules 0.0.6

Steps to reproduce:

1. Start with a fresh vite create vite@latest app --template react-ts
2. Make sure build.sourcemap is set to true in vite.config.js
3. npm run build
4. Notice the built files in dist has a working JS sourcemap
5. npm i vite-plugin-inline-css-modules
6. import { inlineCssModules } from vite-plugin-inline-css-modulesand call it in theplugins[]invite.config.js`
7. npm run build
8. Notice the built files in dist has a broken JS sourcemap (with much lower file size compared to previous)

hey @kp-entrust ! Can you try with vite-plugin-inline-css-modules@0.0.7? I disabled sourcemap generation and it seemed to get rid of the warnings and sourcemaps still seem to be working as expected.

That seems to have worked. Thank you!
