No newlines between uses

Because types are not specified in docblocks but directly in code, which is even more true with PHP 8 and union types.

Because

```
use Something;

use SomethingElse;

private Foo $foo;
private Bar $bar;
```
looks better when written like
```
use Something;
use SomethingElse;

private Foo $foo;
private Bar $bar;
```
