Currently the command teams channel get get's channel information based on teamId and channelId, to make it more human readable let us introduce options teamName and channelName as well.
Use either teamId or teamName but not both to identify the Microsoft Teams Team.
Use either channelId of channelName but not both to identify the channel within the specific Team.
If we find multiple items matching the names (teamName or channelName) return an error with the list of matching items and their IDs to disambiguate.
