I don’t think we’re getting any benefit from it. Especially since we’re
not running any Node code in production, but just using it to build the
frontend.
The downside is we keep getting these massive diffs which means we don’t
get an accurate line count on pull requests.
Followed instructions here:

`package-lock.json` is a file that newer versions of NPM generated
when installing dependencies.
> It describes the exact tree that was generated, such that
> subsequent installs are able to generate identical trees,
> regardless of intermediate dependency updates.
> This file is intended to be committed into source repositories.
