Send2UE: AnimationCurveNodeWrapper has no attribute 'add-keyframe'

[DanMcLaughlin]

• Addon: Send to Unreal
• Steps to Reproduce the Problem: I clicked Pipeline > Export > Send to Unreal
• Error Log: See below
• OS: Windows
• Addon Version: Send to Unreal 2.4.3
• Blender Version: Blender 4.01
• Unreal Version: Unreal 5.03

Something is different in 4.01 - a lot of breaking changes with the Python API, I'm seeing it in other addons. But also this python error isn't showing up in the error log, I'm only finding it in the popup which I grabbed an image of

The relevant error is in core/io/fbs.py line 159 AnimationCurveNodeWrapper has no attribute 'add-keyframe'. Did you mean 'set_keyframes'?
