Scripts documentation incorrectly states all package.json fields are provided via the environment

[mistydemeo]

According to the scripts documentation, all of the fields in package.json are exposed to scripts via environment variables. However, this isn't true: they were removed in 2021 in npm 7 without replacement. I eventually had to track down the 7.0.0-rc0 changelog to find out what changed and the motivation; it would be great if the docs accurately reflected the current state of what's available for scripts.

There are a few issues about this in the npm repo, a couple of which are still open and mention that the docs are out of date:
npm/cli#3022
npm/cli#2452
