Thanks Pedro! It was that easy, huh?

Hey guys, i've also updated dev dependencies.

There were some issues with tests, I fixed two of them.
The return type of the setUp method and the database name.
The change on return type may be a breaking change, so it's probably better to tag a new version with only l10+ support with PHPUnit 9.5+ ?

Tests are now running and green, but we still have some issues with PHPUnit xml file.
I think the invalid attributes are just disregarded so the tests run fine:

Using PHPUnit 10.x

Using PHPUnit 9.6x

I also tested revisionable on our use case, it seems to be working fine:
