Set engines in package.json

[JamieMagee]

Environment

azure-pipelines-task-lib version: 4.3.1

Issue Description

It's not explicit what version of Node is supported when using the azure-pipelines-task-lib Node library. The dependency on @types/node version 16.x implies that version 4.x supports Node 16 only, but adding the engines property would make it explicit.

Expected behaviour

azure-pipelines-task-lib should explicitly state the versions of Node it supports

Actual behaviour

azure-pipelines-task-lib doesn't explicitly state what versions of Node it supports
