fix: update imagick to use ImageMagick 7.x packages for Debian Trixie

Debian Trixie upgraded from ImageMagick 6.x to 7.x, changing the library
package naming scheme. The old package name causes build failures.

Changes:
- libmagickwand-6.q16-6 → libmagickwand-7.q16-10

Affects 5 Dockerfiles across PHP 8.1-8.5 on Trixie:
- 8.1/trixie/pecl_imagick/Dockerfile
- 8.2/trixie/pecl_imagick/Dockerfile
- 8.3/trixie/pecl_imagick/Dockerfile
- 8.4/trixie/pecl_imagick/Dockerfile
- 8.5/trixie/pecl_imagick/Dockerfile

This follows the same pattern as previous Trixie package updates
(libicu, libldap, libzip, libhiredis, libsnmp, libmemcached).
