PERF: Minify admin and wizard JS bundles to match app (#17992)

Browse Source 
This regressed when we switched these bundles to be compiled by ember-cli. Before/after sizes:

```
          before                  after
admin.js: 1370 KB (190 KB gz) --> 782 KB (125 KB gzipped)
wizard.js: 127 KB ( 22 KB gz) -->  68 KB ( 18 KB gzipped)
```
