Outdated note in Example \#10 on `Types > Arrays` page

Problem

The Note directly beneath Example #⁠10 still says:

As mentioned above, if no key is specified, the maximum of the existing [int] indices is taken, and the new key will be that maximum value plus 1 (but at least 0).

That parenthetical describes behaviour prior to PHP 8.3.0.
Since 8.3 the next automatic key after a negative one is n + 1, exactly as Example #⁠7 and its warning already state.

Suggested fix

Remove (but at least 0) from the sentence and replace Note in Example #⁠10 with this:

As mentioned above, if no key is specified, PHP uses the next integer key: the
maximum existing integer index + 1. If the array currently has no integer
indices, the key will be 0 (zero). For the historical behaviour prior to
PHP 8.3.0 — where appending after a negative key could yield 0 — see Example #7.
