feat(node): support node 20 in tasks

Use Node 20 using microsoft guidance: https://learn.microsoft.com/en-us/azure/devops/extend/develop/add-build-task?view=azure-devops#q-how-can-i-upgrade-my-custom-task-to-the-latest-node

Keep Node 10 as a fallback.

Adding support requires a hacky patch to fix shell.js, which doesn't support bundlers.
Mitigates the issue described in aws#539

Addresses aws#566
