Update internal flems to allow dynamic theming.
This Pr replaces the 'material' theme as default with 'night' in the hosted flems codemirror.
How to test: - You can replace the instances of 'night' inside the run.sh file, with one of the other available stylesheets seen here
run bash run buildflems
and then run bash run dev
locally it should update to the new theme.
