### Godot version

v4.2.dev4.official [549fcce5f]

### System information

Godot v4.2.dev4 - Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 6GB (NVIDIA; 31.0.15.3640) - Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz (4 Threads)

### Issue description

If the folder has assigned a color, the color is reset to default when the folder name is changed. Also subfolder colors are reset.

Also moving a folder resets its and its subfolders' colors.

I would expect that renaming or moving doesn't rest the folder color. Especially if you have a large folder structure with many folder levels and assigned colors, it is a unfortunate to have all colors reset if the top level folder is renamed.

### Steps to reproduce

1. Create folder structure 

```
level1
	level2
		level3
```

2. Set folder colors to `level1` and `level2.`

3. Rename `level1` to `foobar` 

-> All folders are now using the default color.
