refactor(@angular/build): remove direct usage of undici dependency for SSR

The Node.js types (`@types/node`) now contains the information for the `Response`
class and the global `fetch` function. The `Response` object is also globally
accessible in all versions of Node.js supported by the Angular CLI. This removes
the need to depend directly on the `undici` package.
The `undici` package is still used for unit-testing and remains as a development
dependency.
