Bump PHP minimum version to 8.3 (#2899)

#2644 changed the default version of PHP used in our default
Debian-based Docker image. At the time, Red Hat had not released a
RHEL-based image containing PHP 8.3. Red Hat has now released an image
with 8.3, meaning that we can require a minimum version of PHP 8.3 for
all CDash instances.
