Correction needed on amplify downloadData

**Describe the content issue**:
On the web page it provides documentation on how to use downloadData. In the example on downloading a file to in-memory buffer, it starts off with this:

// Downloads file content to memory
const { body, eTag } = await downloadData({
key,
data: file,
options: {
...

The "key" part should really be "key: s3Key" or something similar to explicitly say you need the "key:" part. There is another section later where the same thing occurs. Earlier it does show this.
