[php-src] Issue #14476: PHP version 8.3.8 tagged even though it's not released

Issue: https://github.com/php/php-src/issues/14476 Author: aurimasrim ### Description # Context We are using https://github.com/shivammathur/setup-php for a PHP setup in CI. We noticed today that our CI started to fail even though we haven't made any changes. # Problem We noticed that the CI step is trying to use PHP version 8.3.8 even though it has not been officially released yet. ``` Run shivammathur/setup-php@v2 /usr/bin/bash /home/runner/work/_actions/shivammathur/setup-php/v2/src/scripts/run.sh ==> Setup PHP ✓ PHP Installed PHP 8.3.8 ... ``` I guess this workflow is using tags from GitHub: https://github.com/php/php-src/releases/tag/php-8.3.8 There isn't even a docker image yet: https://hub.docker.com/_/php/tags ### PHP Version 8.3.8 ### Operating System _No response_
