`dba_list()` is now zero-indexed instead of using resource ids

Description

While adding new casters to Symfony, we came across a 8.4 regression. The following code:

<?php

$dba = dba_open('test.db', 'c');
var_dump(dba_list());

Resulted in this output:

array(1) {
  [0]=>
  string(52) "/Users/mac-ADAUBO01/PhpstormProjects/symfony/test.db"
}

But I expected this output instead:

array(1) {
  [52] =>
  string(52) "/Users/mac-ADAUBO01/PhpstormProjects/symfony/test.db"
}

Works fine on PHP 8.3.14. This makes it not possible to gather information with dba_list() by casting the resource/Dba\Connection to integer.

PHP Version

PHP 8.4.1
