Fixes scene corruption when updating dependencies.

This commit fixes issue #17585: renaming/moving resources can corrupt
scene files.  The corruption was caused by
'ResourceFormatLoaderBinary::rename_dependencies' updating the file
format version field of the affected scene file to the latest version
without actually updating the content of the file to that version,
resulting in a file whose content does not match its file format version
field.  The fix preserves the file format version field and the engine
version fields when renaming dependencies.
