Package request: npm-current

Alpine Linux already packages Node.js 16.x as nodejs-current. While this is great, it is little to no use without having the associated package manager npm, which currently has the base nodejs (e.g. version 14) as a dependency.

The suggestion is to build Node.js 16.x linked version as npm-current. The naming would be consistent with the other package and could easily be updated in tandem with updating nodejs-current

Node.js 16 is will be the actively maintained version starting next fall, https://nodejs.org/en/about/releases/ and I think it would be good if alpine packages were prepared for that.
