The `intl` extension could not be loaded

Hi!

The 5.x images do not include the shared object files required for the intl extension:

$ docker run --pull always -it --rm pimcore/pimcore:php8.5-latest php -i | grep intl
php8.5-latest: Pulling from pimcore/pimcore
Digest: sha256:f886c3dcb151465053b28758814e26f888070b435a5c0fe87191e03578382b08
Status: Image is up to date for pimcore/pimcore:php8.5-latest
PHP Warning:  PHP Startup: Unable to load dynamic library 'intl' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20250925/intl (/usr/local/lib/php/extensions/no-debug-non-zts-20250925/intl: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20250925/intl.so (libicuio.so.76: cannot open shared object file: No such file or directory)) in Unknown on line 0

This should be a persistent dependency: https://packages.debian.org/de/trixie/libicu76

Since persistent dependencies can be easy to overlook, this could be an option for installing PHP extensions: https://github.com/mlocati/docker-php-extension-installer

This approach is especially handy: https://github.com/mlocati/docker-php-extension-installer#using-the-script-of-a-docker-image

this one should handle it #244

Thanks for reporting!
