NPM security updates and correction for hiding/showing offer sections

[marteki]

This updates versions for our NPM front-end packages, and corrects an error where the snyk security policy was set to be ignored by Git.

It also corrects the dynamic hiding/showing of offer sections based on URL values to only apply to the anticipated total direct cost and tuition payment plans.

Additions

• npm prune to setup.sh before npm shrinkwrap

  Removals

• .snyk reference from .gitignore, so everyone can share the same updated security policy!

  Changes

• Only hide total direct cost and tuition payment plans if the URL value is $0 or missing entirely. Show all other sections as applicable (based on program or loan availability).
• Add missing values in worksheet.html

  Testing

Pull down the branch. Try a full setup.sh to get a fresh copy of the code.

Try setting the total direct cost to 0 in the URL. Try removing it. Try setting the tuition payment loan amount to 0 in the URL. Try removing it. Try setting anything else to 0 in the URL, or removing it. The sections should still remain.

All unit tests should pass. Our NPM security tests should pass. Browser tests are still not all passing, but have improved their failure rate.
