Deprecated: preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated with PHP 8.1 #474

I'm testing a project where I use jaybizzle/crawler-detect:1.2.109 with PHP 8.1, and it is throwing this error:

Deprecated: preg_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /app/vendor/jaybizzle/crawler-detect/src/CrawlerDetect.php on line 168.

It works fine with PHP 8.0, but I guess it requires some changes to make it compatible with PHP 8.1

I'm open to contribute the fix if you want to.
