ansible: update node from 14 to 16

[MoLow]

Fixes: #3329

I had to use node 16 and not 18 due to nodesource/distributions#1392 (comment).
I guess it is time to start upgrading ubuntu 18 to newer versions

I have ran this on test-equinix-ubuntu2204-x64-1, test-equinix-ubuntu2204-x64-2, test-ibm-ubuntu1804-x64-1

build/ansible/playbooks/jenkins/worker/create.yml

The two packetnet servers are gone and can be removed from the above. They were replaced by the equinix servers.

I'm okay with going to Node.js 16, or attempting to upgrade the IBM Cloud machine (test-ibm-ubuntu1804-x64-1) to Ubuntu 22.04 to match the equinix machines.

This is probably beyond the scope of this PR (which is already deployed)
