Bot needs updating to be deployed

[nzakas]

The last deploy failed, apparently because we're still using Node.js 16.

I tried manually updating everything to use Node.js 20, but that causes all kinds of errors in the CI tests.

As best I can tell, we need to:

1. Ensure we're using Node.js 20 or higher throughout the CI and server
2. Upgrade any dependencies that don't work in Node.js 20+
3. Ensure CI testing works properly

I can take it. 😄
