feat(angular): Add Angular 15 Peer Dependencies

[Lms24]

This PR adds Angular 15 support by adding 15.x as a peer dependency version for the Angular packages. A quick test suggests that all previous features seem to work as usual. Still have to do some experiments with new NG15 features but for now we can at least add basic support and unblock anyone who wants to update to v15.

Aside, maybe it is easier to make this: >= 10 && <= 15? As the list gets longer and longer 😅

Good point 😅
