Fix JS client does not return the expected base URL when using nuxeo-stacks

Using a docker image created by nuxeo-stacks with mongo, elastic, kafka
Using LTS 2023
Using the admin console snapshot package that deploys a standalone app written in Angular at nuxeo/nuxeoadmin
Access the angular app deployed in the server at nuxeo/nuxeoadmin as an administrator (http://nuxeo.docker.localhost/nuxeo/nuxeoadmin/)

The app creates a Nuxeo object without passing any parameters (we cannot guess what the domain URL will be for customers)

=> JS client returns the base URL as http://localhost:8080/nuxeo/ and the REST URL as http://localhost:8080/nuxeo/api/v1/
=> Docker image expects base URL to be http://nuxeo.docker.localhost/nuxeo/ and REST URL to be http://nuxeo.docker.localhost/nuxeo/api/v1/
=> No API call can be done and the app cannot be used

Expected: JS client should return the URL expected by the docker image to call the REST API
