Error in code examples in resource introduction of dojo.io

**Bug**

There are errors in the code examples in resources introduction on dojo.io. Since the resources are a very new addition and there is no widespread use in the public examples so far, these should be fixed, especially the one about the createDataMiddleware function. I just mention the second one as it's in the same document.

Package Version:

Current dojo.io for v.7 : https://dojo.io/learn/resources/introduction

**Code**

**Expected behavior:**

Code example for ResourceAwareWidget.tsx should read:
`const resource = createResourceMiddleware ();`

Code example for App.tsx should read:
`const template = createMemoryResourceTemplate<{ foo: string }>();`

**Actual behavior:**

Code example for ResourceAwareWidget.tsx reads:
`const resource = createDataMiddleware();`

Code example for App.tsx reads:
`const myTemplate = createMemoryResourceTemplate<{ foo: string }>();`
