Persistence improvements

- improved image persistence - if the source image has not really been modified, the original is used, thus avoiding the increase in filesize
- methods `LinkGeneratorInterface::srcSet()` and `ImageStorageInterface::srcSet()` now returns object of type `SrcSet` instead of string
- fixed Imagick installations in Dockerfile
- added Docker image for PHP 8.3
