bump required Php version

[m-graham]

Laravel 10 was supported until February 4th, 2025.

The parser requires Php 8.2, and will throw errors on previous versions.

An example of an error that can happen:

getClosureUsedVariables was added in Php 8.1. Due to it not existing in Php 8.0 it fails.

Error: __VSCODE_LARAVEL_START_OUTPUT__
   Error 

  Call to undefined method ReflectionFunction::getClosureUsedVariables()
