Merge branch 'maintenance/update-dependencies' into develop

Updated all NuGet and npm dependencies to their latest versions. All of the NuGet updates only affect design- or build-time dependencies, and won't affect downstream consumers. That's also true of some of the npm dependencies, but there are also updates to some libraries used directly in the front end, such as jQuery UI, jQuery Validation, and Popper.js. Those have been carefully tested to ensure they continue to work as expected.
