Support PHP8.3

[augusl]

Describe the feature you would like to see

Problem 1

• Root composer.json requires kreait/laravel-firebase ^5.2 -> satisfiable by kreait/laravel-firebase[5.2.0, 5.3.0, 5.4.0].
• kreait/laravel-firebase[5.2.0, ..., 5.4.0] require php ~8.1.0 || ~8.2.0 -> your php version (8.3.0) does not satisfy that requirement.
