## Current Behavior
<!-- This is the behavior we have today -->
Setting global styles as entry points in rspack causes HMR to fail


## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
Rspack does not require styles to be set as entrypoints as it will be
handled by the CssExtractPlugin.
Remove the entries
