Remove audit fix during docker build

Doing an audit fix during docker build makes the output more
unpredictable. And we have dependabot in place to update the listed
dependencies.

It also will cause errors for dependencies that it can't fix. We are
using an older version of bootstrap, which has a XSS issue in it. But it
doesn't impact us based on our use of bootstrap. We can't upgrade
bootstrap without significant work, so for now we want to ignore this
issue. npm audit doesn't provide any way to ignore specific
dependencies.
