Update docs: npm is not shipped with nodejs since 0.12.2-4

[reaon]

Please add npm to first code here: https://docs.nodebb.org/en/latest/installing/os/arch.html
npm is not shipped with nodejs since 0.12.2-4; It should be installed manually.

Gah, seriously? Or is this just Arch... nodejs installed via ubuntu (or chris-lea PPA) would bundle npm still, no?

• npm does not work with Python>3.0.0 --> npm config set python python2.7
• npm's ssl certificate problem! --> npm config set registry http://registry.npmjs.org --> http instead of https

@julian It makes sense to keep npm as "optional dependency" since it's not necessary to run an nodejs-application. So it's absolutely valid for my point of view.

Funny fact: even the node.js-wiki didn't add it yet (even so they mention npm separated e.g. for fedora) https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager#arch-linux
EDIT: just added

• To be a bit more clean you may consider using python2 (symlinks to python2.7 for now) instead of directly python2.7
• I haven't heard of this yet, any source for me to read? The only issue I found (within fast search) would require a pretty outdated version of npm to happen...
