Run npm audit

This syncs our dependencies to the latest version. There is still
a reported vulnerability in postcss, but we are luckily unaffected.
However, we can't upgrade postcss yet, as stylelint requires it
and can not use postcss 8 yet:
https://github.com/stylelint/stylelint/issues/4942#issuecomment-823513767

Also updated manage_node_deps.py to not run the full install when
running `ls`, to allow for easier inspection of our dependency graph.
