Only show Leave Group options if user has "leave-channel" permission

[nuno-vieira]

🎯 Goal

Hide the " Leave Group" button/actions if the user doesnt have the permissions.

Original PR: #630 by @bpollman

Moved to this new branch in order for CI to run.

🛠 Implementation

NOTE: Depends on update to mocks main swift rep: GetStream/stream-chat-swift#3478

The code checks for"delete-channel" but not "leave-channel"

This new code

    public var shouldShowLeaveConversationButton: Bool {
        if channel.isDirectMessageChannel {
            return channel.ownCapabilities.contains(.deleteChannel)
        } else {
            return channel.ownCapabilities.contains(.leaveChannel)
        }
    }

properly reflect the existing logic that sets the leave/delete title here.

    public var leaveButtonTitle: String {
        if channel.isDirectMessageChannel {
            return L10n.Alert.Actions.deleteChannelTitle
        } else {
            return L10n.Alert.Actions.leaveGroupTitle
        }
    }
