Production webhook for importing n8n into open-webui does not work

In the following line of the README it states that you should use the production webhook of your local N8N instance in open-webui, which is http://localhost:5678/webhook-test/invoke_n8n_agent by default:

           9. Click on the gear icon and set the n8n_url to the production URL for the webhook

However, since open-webui is running from docker, it cannot reach localhost on the host pc. Therefor the localhost part of the url should be replaced with n8n, which would make it: http://n8n:5678/webhook-test/invoke_n8n_agent
