Add resignsFirstResponderOnScrollDown to MessageListConfig

N/A

🎯 Goal

Add a config option to control whether scrolling down on the message list dismisses the keyboard (resigns first responder)

🛠 Implementation

In MessageListConfig we add a new property - resignsFirstResponderOnScrollDown: Bool with a default value of true (existing behaviour). This is backwards compatible, existing code uses the default value.

🧪 Testing

If the MessageListConfig has resignsFirstResponderOnScrollDown = false, scrolling on down on a chat should not hide the keyboard.

🎨 Changes

In the following example, the config resignsFirstResponderOnScrollDown has been changed from the default true to false - and we can see the keyboard is not dismissed when the chat is scrolled.

Note: I assume the checklist step "Affected documentation updated (docusaurus, tutorial, CMS (task created)" is for the repo maintainers, as I can't find documentation in the repo itself. The page which needs updating is this one: https://getstream.io/chat/docs/sdk/ios/swiftui/chat-channel-components/message-list/#message-list-configuration
