feat(telegram): register command menu and menu button on bot start

Add setMyCommands and setChatMenuButton to the Telegram Bot API client
and register a 12-command menu with a commands-type menu button when a
bot runtime connects. Menu setup failures are logged as warnings and do
not block startup.
