Enable intersphinx by hosting objects.inv

Is your feature request related to a problem? Please describe. I would like to link to parts of the geoviews documentation using the sphinx intersphinx extension. I’m 90% sure this used to work, but doesn’t any more. The main thing is that there needs to be a /objects.inv hosted in the documentation. My understanding is this happens by default with normal sphinx builds:

https://www.sphinx-doc.org/en/master/usage/extensions/intersphinx.html

Describe the solution you’d like

https://geoviews.org/objects.inv

Is it possible this file is not being included on purpose? Sphinx is still being used for documentation site generation, right?

Finally fixed, sorry for the delay.

It might have been deliberate, but mistaken.

Here’s an example of the file being removed from the geoviews website build:
