When a help element in the Firefly UI is clicked from within the Firefly JupyterLab extension, the UI constructs a URL for the online help (to be opened in a new browser tab) based on the JupyterLab URL, e.g., something like "https://lsst-lsp-int.ncsa.illinois.edu/nb/user/gpdf/onlinehelp#id=visualization.imageoptions", rather than from the deployment URL of the Firefly server itself.

This makes the help inaccessible.

Two possibilities seem to exist:

1. Figure out how to inform the Firefly JupyterLab extension client-side (JavaScript) code of where the online help server actually is; or
2. Redirect the auto-generated URL shown above (e.g., with an ingress rule) so that it works.

The latter (#2) seems less appealing, as it hijacks a name in the Nublado (notebook) subtree of URLs.

Triggered by the deployment of the new Firefly online help system in the RSP environment.
