Dictionary types - type enum is int in editor

[MarkoGrbec]

Tested versions

Reproducible: 4.4-Dev2

System information

Linux manjaro

Issue description

in editor it doesn't show enum key string but it does int instead

I thought it would show enum key string

when adding new key pairs it works fine but after that it shows int

Steps to reproduce

1. create 2 codes as follows as a resource first one I have autoload 2. one
   and MP is node 2. one

class_name EntityObject extends Resource

@export var dict_transform_tool__results: Dictionary[Enums.Esprite, Variant] # it's Variant for now later it'll be Array[Enums.Esprite]

extends Node

@export var container: Array[EntityObject]

2. than go to the node MP add key pairs (works fine till now)
3. when added it shows number instead of .find_key(number)

Minimal reproduction project (MRP)

class_name EntityObject extends Resource

@export var dict_transform_tool__results: Dictionary[Enums.Esprite, Variant] # it's Variant for now later it'll be Array[Enums.Esprite]

extends Node

@export var container: Array[EntityObject]

Bugsquad edit: Fix code block formatting.

This is point 4 from #78656 (review):

The inspector part can be improved in the future. Currently, keys are displayed as string representations, which is not very convenient for viewing and editing.

I think we could replace string representations with editors:
