Fix vulnerabilities

[sdras]

• We were getting a warning about a vulnerability in hoek, so updated I updated it to fix npm i hoek so it would dynamically update all instances.
• In the process, saw that we had a few more vulnerability warnings, so ran npm audit fix to update 9 other high vulnerabilities- (68 reported in all, low through high)

Hm, deployment failed, looks like Netlify needs a higher version of node to be compatible with the higher hoek version. One sec.

Ok, this should do it. But please note that I'm also adding in node engine details here in order to get this done.
