lockfile/6.0.md and dependency-paths

[CraigMacomber]

I was reading https://github.com/pnpm/spec/blob/master/lockfile/6.0.md and noticed some things:

### lockfileVersion

A [ComVer](https://github.com/staltz/comver) starting with the major number `4`.

### packages

This is a mapping of dependency path to dependency object. The [dependency path](../dependency-path.md) is relative (e.g., `/[email protected]`) if the dependency
is from the registry specified in the registry property, or absolute (e.g., `registry.node-modules.io/[email protected]`) if the package's
registry differs from the one specified as default in the shrinkwrap file.
That should say 6 right?

I think the major version is 6 now, not 4.

Also dependency-path.md describes a format that seems like the one use in v5 lock files, not the one used in v6 lock files. There was a change to the format between v5 and v6 (I see /mime/1.6.0 change to /[email protected] and /webpack-cli/4.10.0_fzn43tb6bdtdxy2s3aqevve2su replaced with /[email protected]([email protected])([email protected])([email protected]) when updating for example). This change does not seem to be documented anywhere that I can find.
