Outdated package.json file

[ltfschoen]

• After installing Node.js 18.6 LTS, when I ran npm install it output the following as the package.json file in this repo has outdated dependencies

  
  root@ink:/app/dapps/evm/flipper# npm install
  npm WARN deprecated testrpc@0.0.1: testrpc has been renamed to ganache-cli, please use this package from now on.
  npm ERR! code ECONNRESET
  npm ERR! network aborted
  npm ERR! network This is a problem related to network connectivity.
  npm ERR! network In most cases you are behind a proxy or have bad network settings.

npm ERR! A complete log of this run can be found in: npm ERR! /root/.npm/_logs/2023-06-20T04_24_15_857Z-debug-0.log

* To fix it I had to run the following to update all dependencies in package.json to new major version. I think this command should be used in this repo, or use https://github.com/dependabot/dependabot-core
```bash
npm outdated
npm install -g npm-check-updates
ncu -u
npm update

• Then I was able to install dependencies

  npm install

hey there! so i'm not seeing the same errors with node 18.6 when i run npm install and i checked to see how outdated the packages are and there aren't any major version bumps to the packages for this repo, all just minor versions bumps:

 @openzeppelin/contracts      ^4.6.0  →   ^4.9.2
 @truffle/hdwallet-provider   ^2.0.8  →  ^2.1.12
 truffle                     ^5.5.13  →  ^5.10.2
 truffle-plugin-verify       ^0.5.25  →   ^0.6.4

i did a quick search and came across this issue that was opened a little while ago, but may still provide some insights into the error you're seeing: https://github.com/npm/npm/issues/7945

• are you on windows/linux/mac?
• what version of npm are you using?
• do you have truffle globally installed? if so, what version of truffle are you running?

I at the least submitted a PR to bump the packages to the latest versions. Thanks for bringing that up!
