Migrate to npm

[rzhao271]

While looking into Component Governance alerts for this repository, I noticed that

1. Dependencies are locked to specific versions, which makes bumping packages harder.
2. Some dependencies such as telemetry-extractor are years out of date.
3. yarn upgrade X does nothing, probably because of 1.

I suggest migrating to npm and using ^ along with the version numbers so that most CG alerts can be resolved with npm audit fix or dependabot.
