Bug#1084781: pydata-sphinx-theme missing templates etc

[Rebecca N. Palmer]

The current pandas lets the documentation fail as a workaround for this, 
which is also an option for anything else that uses pydata-sphinx-theme 
and urgently needs to be uploaded, but is obviously not a real solution.

Adding 'stb compile' to the build *maybe* worked, but not reliably (and 
I'm not sure if it's using the installed nodejs or downloading one) and 
some tests still fail:
