Fix missing environment files for `safevalues` NPM package

The NPM package is missing the `environment/*` files, referenced by e.g. `restricted/reviewed.js`, causing errors like:

```
./node_modules/safevalues/restricted/reviewed.js:5:0-28 - Error: Module not
found: Error: Can't resolve '../environment/dev' in
'X/projects/angular/aio/node_modules/safevalues/restricted'
```
