Add scriptProperties values as placeholder to the pagination

Add scriptProperties values as placeholder to the pagination. This is quite useful, if you need to fill special properties into special placeholders in the pagination links. Otherwise you have to create several pagination chunks with the special properties.

If for some reason it turns out to be null, array_merge(null, $pagination) will throw an error in PHP 8+.

Let's add some protection:

$pageNavVar => !empty($tplPageWrapper)
 ? $pdoPage->pdoTools->getChunk($tplPageWrapper, array_merge((array) ($scriptProperties ?? []), $pagination))
 : $pdoPage->pdoTools->parseChunk('', array_merge((array) ($scriptProperties ?? []), $pagination)),

or

$pagePlaceholders = array_merge((array) ($scriptProperties ?? []), $pagination);
$pageNavVar => !empty($tplPageWrapper)
 ? $pdoPage->pdoTools->getChunk($tplPageWrapper, $pagePlaceholders)
 : $pdoPage->pdoTools->parseChunk('', $pagePlaceholders),

I am quite sure that $scriptProperties is an array all the time. Otherwise the code will break before.
