Steps to replicate the issue (include links if applicable):

• Install WikiSearch latest version 8.0.1 (2024-07-25) on MW 1.43

What happens?:

The following deprecation error occurs:

[22-Jan-2025 15:19:05 Europe/Berlin] PHP Deprecated:  Use of wfGetDB was deprecated in MediaWiki 1.39. [Called from WikiSearch\WikiSearchHooks::searchConfigCallback in /var/www/html/extensions/WikiSearch/src/WikiSearchHooks.php at line 300] in /var/www/html/includes/debug/MWDebug.php on line 385

The WikiSearchHooks.php calls wfGetDB multiple times:

# grep wfGetDB /var/www/html/extensions/WikiSearch/src/WikiSearchHooks.php
                SearchEngineConfig::delete( wfGetDB( DB_MASTER ), $id );
                SearchEngineConfig::delete( wfGetDB( DB_MASTER ), $article->getId() );
                $database = wfGetDB( DB_PRIMARY );

What should have happened instead?:

wfGetDB should be replaced in order to avoid deprecation errors
