docs: update tutorials to use v18 (#56043)

All documentation tutorials will now use the recently released version 18
of Angular. Additionaly, the tutorials have been migrated to use the new
`@angular/build` package which does not contain the Webpack related dependencies.
The `first-app` tutorial was not moved to `@angular/build` due to it having
karma related dependencies present which currently requires the Webpack-based
build system during test execution.
