Orca build references non-existent mathjax dep

[BRONSOLO]

The mathjax download performed here:

orca/deployment/Dockerfile

Line 85 in c68d3df

RUN curl -L https://github.com/plotly/plotly.js/archive/master.tar.gz \

will need to be updated as of: plotly/plotly.js#5487.

Mathjax is now installed via npm in plotly.js here: plotly/plotly.js#5494

@BRONSOLO is this blocking you?

[BRONSOLO]

Thanks @antoinerg! It's not blocking anything at the moment but will be a blocker if we ever have to make a new Orca release for 4.1.X so it would probably be safest to tackle sooner rather than later if possible (fyi @plotly/platform).
