fix(@schematics/angular): default component templates to not use .ng.html extension

To align with recent changes to the updated style guide, Angular v20 will now
generate component templates without a `.ng.html` file extension and instead use
the previous `.html` by default. The `--ng-html` option is still available for use if
the `.ng.html` extension is preferred in projects.
