There are several out-of-date or deprecated dependencies and npm audit issues

[ericfitz]

Describe the bug:
There are a number of out of date, deprecated or insecure packages used in the project. These should be updated.

NPM START build warnings:

Browserslist: caniuse-lite is outdated. Please run:
  npx update-browserslist-db@latest
  Why you should do it regularly: https://github.com/browserslist/update-db#readme

(node:642767) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
(Use `node --trace-deprecation ...` to show where the warning was created)

(node:643011) [DEP0044] DeprecationWarning: The `util.isArray` API is deprecated. Please use `Array.isArray()` instead.
(Use `node --trace-deprecation ...` to show where the warning was created)

Expected behaviour:
NPM audit, and builds, should be clean and free of deprecation and out-of-date and insecure warnings or errors.

Environment:

• Version: 2.3.0-RC2
• Platform: Web App
• OS: Amazon Linux
• Browser: Brave (chrome)

To Reproduce:
npm start
npm audit

Any additional context, screenshots, etc:
I am working on a fork that fixes all the out-of-date issues and runs on the latest version of node.js. I will send a merge request when ready.

Hello @ericfitz , thanks for raising this issue and it is certainly been a long running problem
If you can get some of these fixed that would be great: mainly they are a result of various third party libs that may be difficult to upversion - please see what you can do
I have assigned it to you and tentatively marked this for version 2.3.1 due for release next month, but if you need more time then version 2.4 is due mid year
