[BUG]: Remove duplicate nixl_connect implementations

[rmccorm4]

Describe the Bug

Latest nixl_connect API / docs were moved into dynamo python package here: https://github.com/ai-dynamo/dynamo/blob/main/lib/bindings/python/src/dynamo/nixl_connect/__init__.py

A duplicate exists in the multimodal python example here: https://github.com/ai-dynamo/dynamo/blob/main/examples/multimodal/connect/__init__.py

Same for the README.md in both places, which are slightly different.

The duplicate implementations and READMEs should be removed in favor of the packaged one, and the multimodal example should be tested that it still works as expected after removing the duplicate.

https://github.com/ai-dynamo/dynamo/blob/main/examples/multimodal_v1/connect/__init__.py was removed about a week ago.

Thanks @whoisj , updated the link to be multimodal instead of multimodal_v1, but this is still an open issue to fix.

#2622 should resolve this issue then.
