`ng add @angular/elements@next` fails with schema.json not found error

See original GitHub issue

🐞 bug report

Affected Package

The issue is caused by package @angular/elements

Is this a regression?

Yes. Doing ng add @angular/elements works fine.

Description

Creating a new workspace project using angular 9 RC 12. Everything installing fine, but when doing ng add @angular/elements@next I get:

`An unhandled exception occurred: Path "<my_dir>/node_modules/@angular/elements/schematics/ng-add/schema.json" does not exist.
See "/private/var/folders/9c/scyzyh01349gnx6qgkp_twzh0000gn/T/ng-GPnlhg/angular-errors.log" for further details.

Log shows:

Probably in 9.0.1. Patch releases are usually weekly.

Just a note; schema.json is also not present in earlier versions of @angular/elements; checked a couple of versions at unpkg: 6.x, 7.x, 8.x.
