3D in examples mostly not showing anymore

[stupor-mundi]

A few days ago I was able to see most of the official examples in 3D.
Yesterday and today, for me only the https://openlayers.org/ol-cesium/examples/oldfashioned.html still works in 3D.
The others merely show black.
I suspected something locally broken with my browser, but tried other browsers, same result. Also when using VPN.
OTOH, when looking at the Cesium sandcastle examples those work as usual.

Hi @stupor-mundi , thanks for the report. I guess this will be solved by #1004 (once it is deployed) .
Maybe it was due to the very old version of node we were using in the CI.

Examples weren't working in my local install (git pull and then npm install). Downgrading Cesium to 1.98 fixed it. See #1014 , #1010 and #985
