PHP 8.5 Compatibility

[swissspidy]

Getting some deprecation warnings:

Deprecated: Method PDO::sqliteCreateFunction() is deprecated since 8.5, use Pdo\Sqlite::createFunction() instead in /.../wp-content/mu-plugins/sqlite-database-integration/wp-includes/sqlite/class-wp-sqlite-pdo-user-defined-functions.php on line 34

Otherwise seems fine at first glance.

I tried to run all unit tests with PHP 8.5 in #235, but I'm confused about why I see no deprecations: https://github.com/WordPress/sqlite-database-integration/actions/runs/17492452396/job/49685179930

It appears they should be reported 🤔

Maybe that particular code path is not tested or so?

The PHP version looks correct though, the latest nightly already includes the deprecation (see php/php-src@a4afc57)
