Update dependencies
- Upgrade Redux and related libs
- Upgrade enzyme-adapter
- Minor upgrade to react-select
- Upgrade jspdf to v2.4
- Move react-scripts to devDependencies
- Regenerate lockfile
This fixes some issues; I'm still getting Dependabot security warnings. Unfortunately a lot of those are based on create-react-app, and I'm on the latest version. I moved that to non-runtime dependencies in an attempt to mitigate this. Switching to something else would be time-consuming.
