Document minimum node v12 & v14 versions in README.

[delhanty]

Further to my earlier comment:

Edit: looks like the minimum versions are v12.20 and v14.13.1. I will make a pull request to document this in the README.

#1000 (comment)

That references:

Node.js 14.13.0 added support for named CJS exports, see #35249 and this change has also been backported to Node.js v12.20.0.

nodejs/node#32137 (comment)

and

Yep, it was fixed after downloading 14.13.1, thank you

Rather than documenting this, we've enforced it here:

kit/packages/kit/package.json

Line 78 in 6f10193

"node": ">= 12.17.0"

It looks like that line should be changed to >= 12.17.0 || >= 14.13.1

Ah great!

A friend (@a-ogilvie below) suggested pretty much that to me just now

"engines": {
  "node": "^12.20 || ^14.13.1 || ^16"
}

but I'm much happier with you messing with the package.json than me!

I note in Discord in the #sveltekit channel there are people trying to build with really ancient versions of node, so hopefully this should save on support time.

@benmccann Will this pattern also match against 14.0 since it's "greater than" 12.17?

@benmccann for v12, the minimum version of node required is v12.20.0.

I guess I close this pull once engines gets updated in master ...
