This PR fixes an issue when you use React with Webpack/Rspack, and
aren't using `@nx/webpack/plugin` or `@nx/rspack/plugin`.
<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->
## Current Behavior
Project configuration contains this for build options:
```
"styles": ["src/myapp/styles.tailwind"]
```
## Expected Behavior
It shoud be :
```
"styles": ["src/myapp/styles.css"]
```
Which is what we actually generate.
