Doesn't work with new versions of data

```
composer require atk4/data
composer require atk4/api
```

will produce an error
```
  Problem 1
    - Root composer.json requires atk4/api ^0.3.0 -> satisfiable by atk4/api[0.3].
    - atk4/api 0.3 requires atk4/data ^2.0 -> found atk4/data[2.0.0, ..., 2.4.0] but it conflicts with your root composer.json require (^5.0).
```
