Incorrect argument type definition in `addHtml` method

[mskocik]

Version: latest

Bug Description

Method addHtml() has mixed type definition, which is incorrect. In fact it really expects HtmlStringable|string, because of inner call of ->insert().

The same applies to addText().

Steps To Reproduce

Html::el('span')->addHtml(0); // results in following TypeError

TypeError Nette\Utils\Html::insert(): Argument #2 ($child) must be of type Nette\HtmlStringable|string, int given

Expected Behavior

No type error being thrown

In current master, addHtml() already has the strict signature addHtml(HtmlStringable|string $child), so the type mismatch with insert() no longer exists. Passing addHtml(0) now throws a TypeError directly on addHtml() with a clear message instead of leaking through to insert() — that's the intended behavior (strict typing rather than implicit string casting). Closing as resolved.
