build(deps): ensure “Gallium” runtime & toolchain

* Begin specifying the Last Known Good Release of Node.js toolchain,
  which is the 1ˢᵗ version of the “Gallium” LTS release line.

Refs: nodejs/node#40536 (review)

> This release marks the transition of Node.js 16.x into Long Term
> Support (LTS) with the codename “Gallium”. The 16.x release line
> now moves into “Active LTS” and will remain so until October 2022.
> After that time, it will move into “Maintenance” until end-of-life
> in April 2024.

Refs: https://github.com/nodejs/node/blob/main/doc/changelogs/CHANGELOG_V16.md#16.13.0

* Begin specifying that we would like to use globally-installed npm.

> While `npm` is a valid option in the “packageManager” property, the
> lack of shim will cause the global npm to be used.

Refs: https://nodejs.org/docs/v16.13.0/api/corepack.html#corepack_how_does_corepack_interact_with_npm

> If the value corresponds to a supported package manager, Corepack
> will make sure that all calls to the relevant binaries are run
> against the requested version, downloading it on demand if needed,
> and aborting if it cannot be successfully retrieved.
