Rename app from hello-edge-and-node to web3-starter in README and package.json

[nickytonline]

Describe the bug

This doesn't affect the application, it's just some cleanup. The project was originally called hello-edge-and-node as this starter was based on their tech stack for dApp development. Since then, I rebranded the project as web3-starter.

The package.json needs to have the project renamed, and there are some places in the README as well that need to have hello-edge-and-node replaced with web3-starter.

package.json

{
-  "name": "hello-edge-and-node",
+  "name": "web3-starter",
  "version": "0.1.0",
  "private": true,
...

I don't believe there is anywhere else it has the old name, but search the project for the text hello-edge-and-node to be sure.
