Renaming property while overrides are active does not rename overrides

[bitbrain]

Godot version: 4.5

Step 1. Define new property on item category
Step 2. Add override on an item on child category
Step 3. Rename property name

Expected: the overrides correctly reflect the new property name
Actual: overrides do not have property name changed, causing a terrible consequence: data gets corrupted:

1. Inside entity.gd it is not not possible any longer to read the property (because it does not exist)
2. Instead of aborting the entire save, Pandora will skip the affected entity

As a result, any item with an override is suddenly deleted from Pandora.
