* feat(image-zoom): add image zoom functionality and documentation - Introduced a new `imageZoom` parameter in the configuration to enable click-to-zoom for Markdown images. - Updated the `render-image.html` layout to support zoom functionality by adding a `data-zoomable` attribute to images. - Created a new `medium-zoom.html` script to handle the zoom effect, with options for CDN or local asset loading. - Enhanced documentation in `configuration.md` and `markdown.md` to guide users on enabling and configuring image zoom. * docs(image-zoom): add image zoom documentation in multiple languages - Added sections for image zoom functionality in Persian, Japanese, and Simplified Chinese documentation. - Included configuration examples for enabling and disabling image zoom in specific pages. - Updated related documentation to ensure consistency across languages.
