No imagick release compiles against PHP 8.6: 3.8.1 still uses zval_dtor() and XtOffsetOf(), both removed in PHP 8.6 (see php-src UPGRADING.INTERNALS). The XtOffsetOf fix (Imagick/imagick#795) is merged but unreleased, and the zval_dtor fix (Imagick/imagick#768) is still open. Installing imagick without pecl is also pending docker-library#1001 (pie). Until then, PHP 8.6 images skip imagick and its build-only -dev packages; WordPress falls back to GD for image processing. The PHP 8.2-8.5 output is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

This is in response to docker-library/php#1654 which means that we have to migrate to
