Description

The default bot implementation throws an error, see below, when an adaptive card (non text) message is sent to it.

Steps to reproduce

Scaffold a new project with a bot and a messaging extension.
Run it (gulp serve) and use the message extension in the bot chat and post an adaptive card to the chat

Expected results

At least no errors in the console

Actual results

When a user would like to use yarn, it needs to be installed, even when --skip-install option is used.
I think this check could be moved to the actual install phase, simply throwing a warning like "Yarn is not installed, skipping install. Please install yarn on your machine." is enough.
What do you think, @HaNdTriX ?

Running jhipster-generator-nodejs using the Docker instructions in the readme.md returns an error.
Dependency resolution for nest fails and there is a lint error that prevents it from completing. However some files are generated.
I am using MacOS and Docker Desktop. I did notice it appears to be still using node 12, would 16 work better?
