Accessing Models using `require()` will no longer work on ember-data v5

[Pixelik]

• ember-data 5.x only allows accessing Models via the Store
• I have created #2502 that will remove the following Deprecation Warning:

Instead of accessing a Model with:

// ember-cli-mirage/ember-data.js

let modelName = matches[1];
let model = require(path, null, null, true).default

It will now be accessed with:

// ember-cli-mirage/ember-data.js

let modelName = matches[1];
let model = application.__container__.lookup('service:store').modelFor(modelName)

And per https://github.com/miragejs/ember-cli-mirage/issues/2445 the idea of auto-discovering models for ED will probably go away as well
