Allow returning string on getCurrentEntryId()

[Chemaclass]

WHY

BEFORE - What was wrong? What was happening before this PR?

The current PHPDoc works only when using int IDs
But uuid and ulids are strings

AFTER - What is happening after this PR?

the returning type is correct, allowing also to return string (additional to the previous types)

HOW

How did you achieve that, in technical terms?

Updating the phpdoc

Is it a breaking change?

no

[welcome]

BOOM! Your first PR with us, thank you so much! Someone will take a look at it shortly.

Please keep in mind that:

• if this constitutes a breaking change, it might take quite a while for this to get merged; we try to emulate the Laravel release cycle as much as possible, so developers can upgrade both software once; this means a new big release every ~6 months;
• even if it's a non-breaking change, it might take a few days/weeks for the PR to get merged; unless it's a no-brainer, we like to have some community feedback on new features, before we merge them; this leads to higher-quality code, in the end; we learnt this the hard way :-)
• not all PRs get merged; sometimes we just have to hold out new features, to keep the packages lean; sometimes we don't include features that only apply to niche use cases;
• we're not perfect; if you think we're wrong, call us out on it; but in a kind way :-) we all make mistakes, best we learn from them and build better software together;

Thank you!
