Update FY 2021 Cancer Moonshot and Carryover Obligations chart to load data from JSON file

The FY 2021 Cancer Moonshot and Carryover - Obligations by Mechanism 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/moonshot-obligations.js
