🎯 Goal

Fix PollOptionAllVotesView not updated on poll cast events.

📝 Summary

SwiftUI PR from: GetStream/stream-chat-swift#3849

🛠 Implementation

Like UIKit, we now observe poll changes in the all votes list view to update the number of votes.

Note: No tests exist for this view model, so for now, I did not add them as well, since it is a simple fix either way.,

🎨 Showcase

🧪 Manual Testing Notes

• Open Demo App with SwiftUI ENV
• Open with Darth Maul
• Open with Leia Organa
• With Leia organa open "Example" channel
• Tap on "View Results" from "Hey" poll
• Tap on "Show All" in the "Two" option
• From Darth Maul device, open the same channel "Example"
• Vote the option "Two", and then remove
• Leia Organa device UI should update correctly
