🚀 Feature: upgrade to Angular 14

[alvaromartmart]

🔖 Feature description

The repo is still at version 13 of Angular. It would be nice to upgrade it to the latest version (14).

🎤 Pitch

Since this is a demo project to showcase setting up an Angular frontend for an Appwrite application, I think it would be good to keep it up to date with the latest versions of the framework.

• For someone relatively new to Angular, this would be a perfect starting point without having to do extra maintenance to upgrade to latest version
• In case that someone needs to maintain older Angular versions, chances are they're already experienced enough with Angular that this would serve as reference material and not a starting project.
