An update to PHP 8.1 and 8.2 (8.3?) is necessary

[gitwalt]

As of PHP 8.1, I receive the following deprecated messages when downloading the PDF:

PHP Deprecated:  Creation of dynamic property BG_Analytics::$file_location_notice_seen is deprecated in /.../job-postings/include/class-bg-analytics.php on line 25
