@ember/renderer work in 2.8.0/2.8.1 not compatible with prior ember releases

Resulting error in both 4.4 LTS and 3.28 LTS

```
Uncaught Error: Could not find module `@ember/renderer` imported from `(require)`

~At a minimum this should have been a major version, but given it doesn't support either LTS likely~ we should fix.
