Seems like relativeTo is deprecated please upgrade to new API

Since Angular 15.2.3 I get the following warning message:

The navigation to /selection/add-edit-product/675670/3 will instead go to /selection/tab-select-diary-item/(outlet-0:search-tab//outlet-1:custom-tab//outlet-2:meals-tab//outlet-3:quickly-add-tab) in an upcoming version of Angular. relativeTo might need to be removed from the UrlCreationOptions.

This seems to be related to the following call:

this.router.back({ relativeTo: this.activatedRoute });

Start with the router.back({ relativeTo: this.activatedRoute }) call described in the issue and compare it with the Angular 15.2.3 navigation warning. Identify the supported API or option change for this navigation, then verify that the warning no longer occurs while navigation to the stated route still works.
