Nice, thanks.
I can merge this, but... I'm actually not supporting version 2. Version 3.x (which I will release soon) already supports PHP 8.3. To release version 3 I actually can use some help with testing it.

@mischabraam Not sure if 3.x version is supporting PHP 8.3. On the composer.json we have

"require": {
        "php": ">=7.1 <8.3",
        "laravel/valet": "^4.5"
    },

Correct, that doesn't matter. :)
Valet-plus requires php 8.1 installed and active on your machine. It doesn't require php 8.1 to actually being linked. It will use php 8.1 no matter the current linked php version.
Next to that valet-plus requires laravel/valet under the hood. Laravel/valet handles all php install support, which includes the installation of php 8.3.
