Upgrade to use PHP 8* and Laravel 5.4*

[SomeDevWeb]

Prerequisites

Just to say, I'm still very new to Laravel, but I started to scratch the surface and I have enough experience in PHP.
I really like the idea of this project, but I have PHP 8.2 and newer Laravel, so I tried to change that in compose.json which fixed the first error, but now I got the new obvious ones.

• Are you running the latest version ? Yes
• Are you reporting to the correct repository ? Yes
• Did you perform a search ? Yes

Description

This is the composer.json line: "laravel/framework": "5.4.*",

Now I get these errors:

Let's take the one by one:
codeclimate/php-test-reporter: https://packagist.org/packages/codeclimate/php-test-reporter
Looking at their page it says: codeclimate-test-reporter - [DEPRECATED], so this should be changed ANYWAY ASAP!!! :)
They also have a new test reporter: https://docs.codeclimate.com/v1.0/docs/configuring-test-coverage

This is where my knowledge stops, but I think that someone from this great team might have some more knowledge and together we can adapt this project to the newest packages.

Anyway, please write some thoughts anyone.
Thanks!
