CSS modules and namedExport, Shakapacker uses default which is not the standard

[justin808]

Need some feedback on the our non-standard way of handling CSS modules. The default for namedExport (true) is not the standard used by other systems like Next.js.

This AI discussion suggests we add a YAML configuration:

# config/shakapacker.yml (template for new apps)
css_modules:
  named_export: false

@tomdracz I marked this as v9.

To clarify, the default is true from webpack.
For v9, let's change the default to false so that css modules work the way of the rest of web tutorials on css modules.
