PHP deprecation error with PHP 8.3.1

@SirClickalot, I have fixed the issue and created Patch file, please review it once.

I confirm that the patch in #3 solves the issue.

Thank you @abhishek_gupta1 →

HOWEVER, after performing (an unconnected with this issue drush updatedb) I have also noticed the following additional offending lines too...

I am also seeing deprecation warnings on other line numbers:

I created the attached patch against 8.x-3.12 to resolve all the deprecation errors in my case...

#7 worked like a charm!

Thanks, but this issue was addressed in the dev branch about 10 months ago. I created a release of it today. Please try 8.x-3.13
