ember data will no longer generate docs in a production build

[Gaurav0]

Related: #74

After this change:
https://github.com/emberjs/data/blob/fbf06f8ba23cc3a41c931e344648e6042ad2b233/packages/-ember-data/yuidoc.json#L6

(which will go into Ember 3.16)

This line will no longer work in ember-jsonapi-docs:

ember-jsonapi-docs/generate-local.js

Line 62 in 5c3d9d8

await runCmd(project === 'ember' ? 'yarn docs' : 'yarn build:production', projDirPath)

We will have to do something different for versions of Ember Data before and after 3.16, because there will no longer be a single command that will generate docs in all versions of Ember Data..

Fixed in b61a267 & this should be backward compatible.
