fix: Support multiple Orchestra Testbench versions for Laravel 10-12 compatibility

The package now accepts orchestra/testbench ^8.0, ^9.0, or ^10.0 to ensure compatibility with different Laravel versions:
- Laravel 10.* requires testbench ^8.0
- Laravel 11.* requires testbench ^9.0
- Laravel 12.* requires testbench ^10.0

This fixes CI test failures across all PHP 8.2/8.3 and Laravel 10/11 matrix combinations with both prefer-lowest and prefer-stable dependency strategies.

Tested locally with:
- prefer-stable: All 243 tests passing
- prefer-lowest: All 243 tests passing (Laravel 10.0.0 + Testbench 8.0.0)
