fakerphp/faker downgraded when installing laracasts/testdummy

[enigmatic-user]

I just created a new Laravel 8 project and then added laracasts/testdummy (which automatically installed version 2.5). When updating the dependencies, fakerphp/faker, which comes with Laravel, was downgraded from version 1.13.0 to version 1.9.2. This was reverted when I removed laracasts/testdummy from the composer.json and updated the dependencies again.

Is the older faker version really necessary for TestDummy, or could the version number be easily changed?
