Fix losing scene modifications when renaming file

Closes: godotengine#30436

When renaming/moving a file in the filesystem docker, changes on a scene that has dependencies on the file being renamed/moved are lost.

To resolve this, this patch saves the scenes that depend on the file first, to save its current state.
