Local install can't pull Internal plugin image

[shrimalmadhur]

Describe the bug
Currently when I do local-install and the node image is not there, it pulls the image from private registry since I have access to it. But when I run plugin command for it, it gives me unauthorized. I can do docker pull and access that plugin image but doesn't work with eigenlayer plugin command.

To Reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behavior
eigenlayer plugin command should be able to pull the internal repo similar to local-install
