Node: Npm bump

I’d like us to consider changing the way we handle npm inside of Node.
Currently, we generally only touch the npm version with each Node
release, but this behaviour contributed a little towards some of the
issues discussed in #31777, because npm releases are outpacing Node
releases considerably.

I’d like us to consider bumping the shipped npm version every 3 minor
releases (1.4.24 to 1.4.27) or every 1 major release (1.4.24 to 2.0.0),
and revisioning the formula to nudge users onto that npm bump.

Rationale:

1) It’ll make debugging less of a pain in the neck, by reducing the
vast environmental variable we currently have between Dave never
updating his npm install, and Sandra constantly updating her npm
install, and anything in-between.

2) It creates less room for things to go wrong towards the end of the
install. A jump of a few versions is generally a lot smoother than a
larger jump. It also means if we do start seeing issues we know it’s
something in a relatively short, fairly-defined timeframe. (Roughly,
this change would ensure that nobody is using npm code older than 5
weeks). This also makes for (marginally) quicker installs for users as
it shortens the npm stage a tiny touch.

3) We’re already adhering to the decision to bump users onto the latest
npm release with each new install, and this roughly follows the same
idea that we want to ensure users are using the newer npm versions.

Potential issues:

1) Theoretically, this could cause #31777 to flare back up more
regularly than it did. I consider this a very low-change risk, based
primarily on bullying the heck out of my system with successive npm
upgrades in this manner over the last two weeks without issues.

2) It’s a wee bit more of a pain for users to have to upgrade Node
every 5 weeks than every 2 or 3 months.

3) It makes the Node formula a little more high maintenance for the
maintainers or me or Bob or Sandra or Dave who propose PRs on this
subject to keep track of npm releases and handle the testing and
revision process. Happy to sacrifice myself for this.

Ultimately, I’ll pass the decision on this over to the maintainers and
their greater knowledge. This is something that has been on my mind &
radar for a while now, but I wholly accept this could be something the
maintainers decide to pass on.
Node: npm bump

A couple of tweaks based on discussions with Mike earlier, and my
desire to caveat the npm update process to avoid the horrific ``` npm
upgrade -g npm ``` disaster.
