Node deletion with multiple links connected to same output throws an "Item not found" error.

## Version of Dear PyGui

Version: 2.0.0
Operating System: macOS 15.1.1

## My Issue/Question

Deleting a node with multiple links connected to a single of its outputs leads to "Item not found" error on some link ids.

Error message:
```
Exception:
Error: [1005]
Command: delete_item
Item: 0
Label: Not found
Item Type: Unknown
Message: Item not found: 40
```

## To Reproduce

Create two nodes with multiple inputs / outputs.
Connect single output of first node to multiple inputs of second node.
Delete first node.
=> Item not found error.

## Expected behavior
Should delete all links cleanly.

```python
import dearpygui.dearpygui as dpg
dpg.create_context()

def link_callback(sender, links):
dpg.add_node_link(links[0], links[1], parent=sender)

def delink_callback(sender, link):
dpg.delete_item(link)

def delNodes(sender):
lst = dpg.get_selected_nodes("node_edit")
for node in lst:
dpg.delete_item(node)

with dpg.window(tag="window", label="Del node bug", width=400, height=400):
dpg.add_menu_item(label="Delete", callback=delNodes)
