refactor: GreetingUtil

[jdegand]

Description

I don't think using a class like GreetingUtil would be considered best practice.

Motivation

Seems outdated to do it like this. Also, there could be extra issues with unit testing, localization, and dependency injection.

Suggested Implementation

(If project is further upgraded) Angular 20 template literals may provide a way to add the same functionality.

Alternate Implementations

You could likely use a service, pipe, or directive to do the same thing.

Thanks, @jdegand, for the feedback. In general, my purpose is to keep this project evergreen/updated, so please be encouraged to contribute a PR with your suggested implementation.
