chore(type): add native return types

[kbond]

Thanks for the PR @mremi. I'm concerned about the potential BC break as none of these methods are final.

Yep, I did it because symfony/error-handler logs all those definitions as deprecated. The alternative could be adding some phpdoc of course, but IMO this BC is a good point to make the code stronger. WDYT?

Out of an abundance of caution, I'd like to go with phpdoc for the non-final/non-private/non-test methods. At least until a time laminas-diagnostics adds true return types or until the next major version of this bundle (this is on my list).

Ok, done, let me know

[kbond]

Thank you @mremi.
