[bazel.build] Problem with /rules/lib/core

[lgalfaso]

Page link:

https://bazel.build/rules/lib/core

Problem description (include actual vs expected text, if applicable):

This page states that the Starlark Language Specification has a data type "json". This data type is not defined in the spec page, nor in the Go implementation spec page.

https://github.com/bazelbuild/starlark/blob/master/spec.md
https://github.com/google/starlark-go/blob/master/doc/spec.md

Where do you see this issue? (include link to specific section of the page, if applicable)

This data type is not specified in the language specification, and given that this page does not contain the specification either, this type is not defined.

Any other information you'd like to share?
