Similar to {T398245}, we need to prepare our own rebuilds of PHP 8.3 and required extension packages for Debian bookworm.
I intend to pick the latest available package versions from https://salsa.debian.org/php-team, which is largely equivalent to what one would get from deb.sury.org as of now.
These are the package versions I expect to pick up (note this list is subject to change until I've actually tried to build them and dealt with any issues that arise):
