Update widgets to match the changes in DuckChat interface (#6624)

Task/Issue URL:
https://app.asana.com/1/137249556945/project/1200581511062568/task/1211103096551754?focus=true

### Description

Refactored the DuckChat widget integration to simplify the process of
opening DuckChat from the search widget.
Removed the `createDuckChatIntent()` method from the DuckChat interface
and implementation, replacing it with a more direct approach that uses
`BrowserActivity.intent()` with an `openDuckChat` parameter.

### Steps to test this PR

Code review.

### NO UI changes
