Sonu Kapoor a7d5c55926 docs: fix routing code to use navigate (#35176)
Previously, the example in the `router` guide was not
preserving the query params after logging in.

This commit fixes this by using `navigate` instead of
using `navigateByUrl`, which ignores any properties in
the `NavigationExtras` that would change the provided URL.

Fixes 34917
