Use more precise return type for count method

[VincentLanglet]

Countable is supposed to return

@return int<0, max>

(vimeo/psalm#8861)

So I would say it's better to rely on inherit doc rather than overriding the return tag ?

If it doesn't break what #353 solves, that looks good indeed.

Yeah, I was wondering if I needed the @return int<0, max> for this...
Is there any test about it ?

Because the LazyCollection use inherit

I just tried in my project @greg0ire and the @return is needed.
So I updated it to @return int<0, max> then. (I get no deprecation this way)

Thanks for triple checking, Vincent 🙏

Technically not a bugfix, but it's OK to target 2.1 IMO because the things it's improving is not released yet.
