Removed Dusk

[marcusmoore]

Description

This PR removes, at least for now, Laravel Dusk since it is not being used locally or in CI.

---

Note: Dusk is mentioned in our upgrade script but I don't think the conditional should be changed. Maybe I should just remove the references to Dusk?

	* It's 100% okay if they're not in production mode, but this will avoid any confusion as they get

	* We use this further down in the composer section of this upgrader.

PR Summary

• Removal of the dusk service
  This change consists of the elimination of the dusk service from our CI/CD configuration file.
• Update of the .gitignore File
  Specific environment settings files used for the dusk service have been removed. However, the example file was kept, allowing other developers to understand the expected format.
• Update of Testing Documentation
  The section dedicated to Browser Tests has been taken out because we're no longer using the dusk service.
• Changes in AppServiceProvider.php
  The DuskServiceProvider is no longer registered in the AppServiceProvider file. This means that we stopped using dusk's specific services within our application.
• Update of composer.json
  The "laravel/dusk" dependency has been removed from the require-dev section of composer.json as we no longer require this package for our development environment.
• Deletion of Specific Testing Files
  Several Dusk-related files including tests, pages, and certain gitignore files have been deleted since they are no longer needed with the removal of the Dusk service. This makes our code simpler and more focused.

I left the existing tests in there so we could (if we wanted to) use them as a guideline, but I'm fine with trashing them.
