Elementor: Social media appearance props not updating upon post content change

[pls78]

Please give us a description of what happened

While working on Add fallback for AVIF for X compatibility, I noticed both TwitterWrapper and FacebookWrapper components don't react to the post content's change. Specifically, the imageFallbackUrl prop doesn't change when it should (i.e., when adding/changing an image in the post body if no social image is specified).
This prevents the solution in the AVIF fallback PR to work in Elementor and might impact also other features.

To Reproduce

Step-by-step reproduction instructions

1. Create a post in the Block editor, add an image in its body and don't set any social image in the Social media appearance section
2. Edit the post in Elementor
3. open the Social media appearance modal from the Yoast sidebar
4. With React DevTools, search for the FacebookWrapper component (pick the innermost one)
5. Verify the imageFallbackUrl prop contains the post's image URL
6. Close the modal and change the image in the post
7. Open the modal again and check the imageFallbackUrl` prop value

Actual results

The prop value is still the URL of the previous image, while it should have been update with the new one.
