Make the navigation tree uncollapsed by default

[bourque]

Since we currently don't have many topics documented yet, we are probably better off having the side navigation bar be 'uncollapsed' by default, so users can see the full list of documented topics. I think this is easy as adding this to the conf.py file:

html_theme_options = {
    "collapse_navigation": False, 
}

I've tried to do this by setting html_theme_options, overriding templates, and using custom JS, but I still haven't achived the desired result of having an expanded ToC on the home page (before the user clicks on any topic).

I'll keep working on this a bit more, but just wanted to give the team a heads-up that this doesn't appear to be a simple change.

Yeah this is a tricky one! I've also tried playing around with this and can't seem to get anything to work 😞
