[bug] The 'extern' directory is missing from comfy-mtb .zip from ComfyUI registry

[xbourque]

Describe the bug

When installing MTB nodes from the ComfyUI Manager, the 'extern' directory is missing from the .zip file downloaded from the ComfyUI Manager at https://storage.googleapis.com/comfy-registry/mel/comfy-mtb/0.4.0/node.zip

This makes MTB nodes fail to import when starting the ComfyUI server.

Reproduction

1. Install MTB nodes from ComfyUI manager.
2. Restart ComfyUI server
3. MTB nodes fail to import with No such file or directory: '/mnt/comfyui_volume/ComfyUI/custom_nodes/comfy-mtb/extern'

Expected behavior

MTB nodes should import when installed from the ComfyUI Manager.

Operating System

Linux

Comfy Mode

In a custom virtual env (venv, virtualenv, conda...)

Thanks for the report... that's unfortunate 0.4.0 is quite old it was a mistake release from the CI and has been marked as deprecated immediatly, I'll ask why the cli resolves to this version.

The latest version is 0.2.1 that addresses precisely this issue (#227)

[xbourque]

Unfortunately, I don't see v0.2.1 in the Manager... I only get v0.1.5, v0.1.6 and v0.4.0 as choices when using the version picker from ComfyUI Manager.

'Nightly' works but the Manager defaults to 0.4.0 when installing multiple missing nodes at once.
