Remove old node gitignore targets

[nycrat]

Description

Like 8 years ago in #110, we implemented a visualizer that used javascript/node. These gitignore targets were added then, but are now causing issues on MacOS where gitignore is case insensitive by default. The specific target *build also targets BUILD files for bazel (I've been manually force git adding these targets and now I realize this was the issue.

This PR just removes these old Node .gitignore targets because they are not relevant anymore.

Testing Done

Checked the repo for all the gitignore targets, they don't exist anymore
