[80999] Fix count TypeError not documented

[thinkverse]

This PR adds the TypeError count() now throws to the changelog, and also updates the example showing that PHP 8.0 throws a TypeError instead of emitting and E_WARNING.

First time adding to a changelog, so not 100% sure if the versions are displayed in descending order or ascending. 🤔  Will change if requested.

Thank you! Descending order is used

It might make sense to split the error cases from the example to their own example, and then have three <screen>s introduced with &example.outputs;, &example.outputs.72; (this entity needs to be defined in language-snippets.ent), and &example.outputs.8. Maybe that would be overkill, though.

[thinkverse]

@cmb69 is that how you wanted it? Never messes with <screen>s and &example.outputs before, so I used foreach.xml as a base. Those are the expected outputs, at least based on the given test example; https://3v4l.org/mMgYD

[cmb69]

Yes, that's basically what I meant (you can remove the "as of PHP ..." comments now). But it may also make sense to split the example, so that the good cases (the first two var_dumps()) and the bad cases (the last two var_dumps()) have their own examples. This would make it possible to have a single &example.outputs; for the good case, and maybe to add some words regarding the bad behavior example.

[thinkverse]

Should the "bad example" example be after the good example then, or should it be added after the recursive example? Cuz count has two examples, the first deals with both a good case and a bad case, the second deals with the recursive aspect of count.

[cmb69]

I'd put the bad example right after the good example.

[thinkverse]

I'm a bit lost on how to "add some words" about the bad example, the title might be enough - I looked around the repo and found a doc using this general idea. Might be OK and get the point across? Otherwise, I'm not sure how to add some words. Can you add notes in or between examples? Those usually go after examples, at least from what I've noticed during my years of looking at the documentation. 🤔

Thank you very much!

Glad to help. 👍
