Division by 0 is impossible, hence, the change.

.avif files in later PHP versions should be handled properly by the getimagesize method (since PHP 8.1 RC3), but we still have to handle older files somehow (dimension values are stored in .xmls in a database).

@konradoboza I don't think there is a need as those are already parsed as strings https://github.com/ezsystems/ezplatform-kernel/blob/1.3/eZ/Publish/Core/Persistence/Legacy/Content/FieldValue/Converter/ImageConverter.php#L115
