Compatibility for PHP 8.2

[MichelleBlanchette]

Got another bug report related to submitting tasks via the Pinned Tasks metabox:

[14-Sep-2023 14:28:45 UTC] PHP Fatal error: Uncaught TypeError: array_sum(): Argument #1 ($array) must be of type array, bool given in /var/www/html/wp-content/plugins/completionist/src/includes/class-options.php:663

The problem is using 0 === array_sum( $dt::getLastErrors() ) because PHP 8.2 allows that function to return a boolean if there's no errors.

So let's do some general testing with PHP 8.2 to check compatibility.

The Asana SDK has compatibility issues per https://github.com/Asana/php-asana/issues/118 but it doesn't seem to be causing functional issues. There's just a lot of Deprecated logs. Nothing I can really do about that anyways, though.
