Update Extramural Funds chart to load data from JSON file

The Extramural Funds highchart currently hardcodes the data for the chart within the .js file. The javascript should load the data from a JSON file uploaded in the CMS.

Chart .js: https://github.com/NCIOCPL/cgov-digital-platform/blob/develop/docroot/profiles/custom/cgov_site/themes/custom/cgov/cgov_common/src/libraries/charts/library/html-extramural.js

Parent Issue: #3008
