Type based on Laravel model ignores regular php properties

Describe the bug

class Test extends Model
{
    public string $test = 'test';
}

type Test {
    test: String
}

This will always return null for test, it never reads the property.

Expected behavior/Solution

It should read the property value.

We are moving away from Laravel get___Attribute getters (which work) as the native php 8.4 virtual property syntax has much better IDE integration and static analysis, so this is a bug that could lead to easily missed mistakes. I guess the implementation uses Laravel array access to retrieve the values, which is imo fine, but it should fall back to trying regular php object properties in case that fails.

Note: A current workaround is using @rename to 'rename' the attribute to itself.

Lighthouse Version

6.57.1

Start by reproducing the issue with the shown Laravel model property and GraphQL type, then trace the model field resolution path that currently returns null. Confirm the existing getter and @rename workaround behavior before changing the lookup. Done means a regular public PHP property resolves its value and the behavior has a regression test.
