feat(service-worker): Add type option to provideServiceWorker

Enables specifying the script type ('classic' or 'module') when registering Service Workers, improving compatibility with ES module features.

The change includes:

• Added type to SwRegistrationOptions interface
• Modified service worker registration to pass the type option
• Added comprehensive unit tests to verify the new functionality
• Updated existing tests to include the new option

Motivation/Use Cases

The type option is particularly useful for:

• ES Module support: Enabling ES module features like import/export in service worker scripts
• Modern JavaScript: Supporting modern JavaScript syntax and module system in service workers
• Compliance with PWA best practices: Aligning with modern service worker registration standards

Proposed Solution

• Add type property to the SwRegistrationOptions abstract class
• Implement property handling in the service worker registration logic
• Pass the option through to the native navigator.serviceWorker.register() API
• Maintain full backward compatibility with existing configurations (defaults to 'classic')

Examples of New Usage

Basic configuration with provideServiceWorker

export const appConfig: ApplicationConfig = {
  providers: [
    provideServiceWorker('ngsw-worker.js', {
      enabled: !isDevMode(),
      type: 'module', // Enable ES module features
    }),
  ],
};
