Laravel 10 Support - PHPUnit/Testbench dependency error

[mwllgr]

Me again, now with Laravel 10. Can't upgrade my project because of this dependency.

When upgrading to PHPUnit 10 ("phpunit/phpunit": "^9.5"):

  Problem 1
    - Root composer.json requires givebutter/laravel-keyable 1.0.0 -> satisfiable by givebutter/laravel-keyable[1.0.0].
    - givebutter/laravel-keyable 1.0.0 requires phpunit/phpunit ^9.5 -> found phpunit/phpunit[9.5.0, ..., 9.6.7] but it conflicts with your root composer.json require (^10.0).

... and when you don't update to PHPUnit 10:

  Problem 1

Used an old package version, my bad. It works as expected with the current state of this repository.
