Reconnect repository workflow should redirect to the app's branch overview page

### Environment information

```plain text
N/A
```

### Description

Currently, when using the `Reconnect repository` workflow once the GitHub App installation completes the user gets redirected to the all apps page in the Amplify console.

Instead, the user should be redirected to the app's branch overview page.

The issue identifies the Reconnect repository workflow in the Amplify console, the GitHub App installation flow, and the all apps and branch overview pages, but names no files or tests. Trace the redirect after installation and determine how the target app and branch are selected. Done means the workflow lands on that app's branch overview page instead of the all apps page.
