TeamsInfo should work with CloudAdapter

[EricDahlvang]

Version

main branch

Describe the bug

SendMessageToTeamsChannelAsync is currently casting the adapter to BotFrameworkAdapter ((BotFrameworkAdapter)turnContext.Adapter).CreateConversationAsync

https://github.com/microsoft/botbuilder-dotnet/blob/main/libraries/Microsoft.Bot.Builder/Teams/TeamsInfo.cs#L233

This should be updated to work with CloudAdapter since it now also supports CreateConversation.
