Updated captions in the Advanced Gallery

Currently, the Advanced Gallery block pulls captions from the WordPress Media Library when adding it to a post. However, when the caption in the Media Library is changed, it will not be updated in the posts. This leaves us with outdated captions across the website. Centrally managing image captions from within the Media Library is essential for large websites, where one image might be used on many pages. Please add an option to have captions updated when pages are rendered in WordPress.
