Adrien Crivelli b0b4953fd6 fix(router): Allow undefined inputs on routerLink (#39151)
This make it coherent with typing of Router.createUrlTree to which
those inputs are directly forwarded to. And hence it allow to pass
`undefined`, `null` or a value to the routerLink directive.

BREAKING CHANGE: in most cases this should not break, but if you were
accessing the values of `queryParams`, `fragment` or `queryParamsHandling`
you might need to relax the typing to also accept `undefined` and `null`.

Angular Router

Managing state transitions is one of the hardest parts of building applications. This is especially true on the web, where you also need to ensure that the state is reflected in the URL. In addition, we often want to split applications into multiple bundles and load them on demand. Doing this transparently isnt trivial.

The Angular router is designed to solve these problems. Using the router, you can declaratively specify application state, manage state transitions while taking care of the URL, and load components on demand.
