Add copy button to Build and Deploy outputs

### Environment information

```plain text
https://{region}.console.aws.amazon.com/amplify/apps/{appId}/branches/{branch}/deployments
```

### Describe the feature

It would be useful to have a copy button for the Build and Deploy output logs. The logs can be quite lengthly, and it is difficult to copy from them manually. Even when doing so, the line numbers are also copied which is unhelpful.

### Use case

When there is an error, it is useful to copy the text out to an external editor so that a search and other actions can be performed on the log text.

Start at the Amplify Console deployments entry point shown in the environment URL and inspect the Build and Deploy output logs. Confirm how the logs are rendered and how line numbers are included. Done means a copy control is available for both outputs and copies the log text without line numbers.
