Node v14 -> v16 updates (npm peer deps)

[c-ryan-k]

This PR updates our actions and pipelines (and package-lock) to successfully install on versions of node/npm that require stricter peer dependencies.

It includes some changes to test files and setup to ensure they run successfully, but mainly relies on the updates to package.json and package-lock.json to enable cross-platform installs on all current versions of npm (8+) and node (16+)
