Fix `Imagick` builds intermittently failing

[Tom Udding]

Current behaviour

Ever since we moved to PHP 8.3 we have had intermittent failures of the Docker image builds due to an issue in the Imagick source. We see the same for the GitHub actions after merging GH-1844.

Desired behaviour

Instead of

    && pecl install imagick \
    && docker-php-ext-enable imagick \

we build from source:

    && mkdir -p /usr/src/php/ext/imagick \
    && curl -fsSL https://github.com/Imagick/imagick/archive/28f27044e435a2b203e32675e942eb8de620ee58.tar.gz | tar xvz -C "/usr/src/php/ext/imagick" --strip 1 \
    && docker-php-ext-install imagick \

Steps to reproduce

Try to build the Docker images and sometimes it will not work.
