The `assets` directory is confusing for the users and commonly users place "assets" which are not meant to be copied but instead processed by the build system. This causes some files both bundled and copied.
With this change we rename the `assets` directory to `public` and also move the `favicon.ico` inside this newly created directory.
With this change we update service worker ngsw-config resources extensions.
- Remove `eot`. Old IE font format. Not supported by browsers which support service worker.
- Remove `ani`. Not supported by browsers.
- Add `jpeg` as common alias for `jpg`.
- Add `apng` as modern alternative to `gif`.
- Add `avif` a modern image format.
Closes#21526
Currently when using `ivy-ngcc` it will print out a warning
```
Failed to read entry point info from //node_modules/@schematics/angular/workspace/files/package.json with error SyntaxError: Unexpected token < in JSON at position 1121.
```
Fixes#13378
* feat(@schematics/angular): account for root level assets and `resourcesOutputPath`
By default we are only account for assets inside the assets folder. Which breaks the offline experience.
Fixes#13067
* test: add test to verify root level assets in service workers
