FetchError: request to http://127.0.0.1:8114/ failed, reason: socket hang up on yarn start

[twhy]

Environment

MacOS 14.4.1
Node v20.12.2

Reproduce Steps

1. Git clone Neuron
2. Follow setup steps in README
3. yarn start

Cause

This is caused by a known issue in node-fetch

Fixed in v2.6.13 node-fetch/node-fetch#1765
Fixed in v3.3.2 node-fetch/node-fetch#1735

The current resolved version of node-fetch in Neuron is 2.6.11

I add "node-fetch": "2.6.13" to resolutions in root package.json to fix this locally.
