Add rearrange to Rewrites and Redirects

### Environment information

```plain text
https://{region}.console.aws.amazon.com/amplify/apps/{appId}/redirects/edit
```

### Describe the feature

Add ability to rearrange redirect rule order.

### Use case

Rewrite rules are applied top to bottom. To add a new rule that needs to be applied first; currently you are required to delete all existing rules, add the new rule, then re-add other rules.

It would be beneficial to be able to drag-sort rules to adjust order.

Start at the Amplify console Rewrites and Redirects editor at https://{region}.console.aws.amazon.com/amplify/apps/{appId}/redirects/edit and trace how redirect rules are displayed and saved. Done means users can drag-sort rules so their persisted order controls top-to-bottom rewrite application without deleting and recreating existing rules.
