[2.x] Remove unused orchestra/testbench deps (#166)

* [2.x] Remove unused `orchestra/testbench` deps

This opens up the opportunity to require and run `tinker` directly from a package using `orchestra/testbench`.

```bash
php vendor/bin/testbench package:discover
php vendor/bin/testbench tinker
```

* wip

* Apply fixes from StyleCI
