Follow recommendation about multiline type

Apparently, there is consensus about multiline types between:

- PHPStan
- Psalm
- Slevomat Coding Standard

See slevomat/coding-standard#1586 (comment)

Using parenthesis is less ambiguous, it makes it clear to the parser
where the type begins and where it ends.

The change has a positive impact on the Psalm baseline, showing
that psalm-return annotation was not really understood previously.
