File/Image delete causes 409 error response on page update

[29avet1]

• Laravel Version: 10.19.0
• Nova Version: 4.27.14
• PHP Version: 8.2

Description:

When we delete a file or image on page edit, then we click the update button, it throws a 409 error "Another user has updated this resource since this page was loaded".
It is caused by the fact that after deleting the image it touches the row in db, sets the image name to null, and also "updated at" is getting refreshed. By this, the "retrieved_at" value is responsible for checking whether another person has edited this resource or not, becomes outdated.
I saw that the nova file input triggers an event "file-deleted", which in "HasOneFiled.vue" is handled and triggers another "update-last-retrieved-at-timestamp" event, which I suppose updates the retrieved_at value to avoid this issue, but in "Update.vue" the "handleFileDeleted" method is empty and not triggering the "update-last-retrieved-at-timestamp" event.

Detailed steps to reproduce the issue on a fresh Nova installation:

1. open the Edit resource page with an image input. upload an image and save, or open an edit page that already contains an uploaded image
2. delete the image, then click the "Update" button. it will throw an error.
