Consider using libnpm instead of spawning npm process

Consider using libnpm instead of spawning npm process in npm plugin

Every piece of information that is currently used by npm plugin can be acquired through libnpm without using npm cli directly.

versions property is sorted by npm cli view command (https://github.com/npm/cli/blob/656bce7dd0f9753a273912e803261ed246593924/lib/view.js#L50)

const packument = require('libnpm/packument');
const semver = require('semver');

packument('libnpm', {
    fullMetadata: true
}).then((data) => {
    const distTags = data["dist-tags"] || {};
    console.log({
        name: data.name,
        description: data.description,
        latestVersion: distTags.latest,
        nextVersion: distTags.next,
        versions: Object.keys(data.versions).sort(semver.compareLoose),
    });
});

Locate the npm plugin and find where it currently spawns the npm process. Compare the information it gathers with the libnpm packument example in the issue, including dist-tags and sorted versions. Done means the plugin obtains the required information without invoking the npm CLI and preserves its current outputs.
