Change the name of promoted widgets in the new edit menu.

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What problem are you experiencing?

Just tried the new menu to promote witges and it works great !

The only drawback for me, is that it does not allow to change the widget name, ( by changing the input slot name ), like the old method. 



### When does this problem occur?

When we have multiple nodes of the same type, in the same subgraph.

### How often do you encounter this problem?

Daily

### How much does this problem affect your workflow?

Causes moderate inconvenience

### Current workarounds

The node badge numbers are shown next to the widget name, but these are only useful if we enable "show badges" and go in to the subgraph.


### Ideas for solutions (Optional)

- In the new menu, we could click on the widget name to change it.

- The original name could be shown next to the custom name, in this menu, like this: `steps_refiner ( steps )`

### Additional context

I also noticed that node badge numbers are being duplicated, when subgraphs are used ( https://github.com/Comfy-Org/ComfyUI_frontend/issues/5913 ), but this issue also happens in old frontend versions, before this feature was introduced.
