Outdated Regexp in npm start task

"regexp": "Compiled |Failed to compile."

The pattern matcher for the npm start task reads

"endsPattern": {
     "regexp": "Compiled |Failed to compile."
}

but since Angular 15+ it should instead be

"endsPattern": {
     "regexp": "Watch mode enabled. Watching for file changes..."
}
