Update Unstructured Docker Image Reference in Documentation

[sarfudheen]

Checklist

• I added a very descriptive title to this issue.
• I included a link to the documentation page I am referring to (if applicable).

Issue with current documentation:

The current documentation at https://js.langchain.com/v0.2/docs/integrations/document_loaders/file_loaders/unstructured/#setup instructs users to run the Unstructured API locally using the following Docker command:
docker run -p 8000:8000 -d --rm --name unstructured-api quay.io/unstructured-io/unstructured-api:latest --port 8000 --host 0.0.0.0

However, the updated link for the Unstructured API (https://github.com/Unstructured-IO/unstructured-api#dizzy-instructions-for-using-the-docker-image) suggests a different command:
docker run -p 8000:8000 -d --rm --name unstructured-api downloads.unstructured.io/unstructured-io/unstructured-api:latest

Idea or request for content:

To ensure users have the most accurate information, please update the documentation at https://js.langchain.com/v0.2/docs/integrations/document_loaders/file_loaders/unstructured/#setup with the following revised Docker command:

docker run -p 8000:8000 -d --rm --name unstructured-api downloads.unstructured.io/unstructured-io/unstructured-api:latest
