Code in help gets executed

[dzschille]

The command warden env-init --help gets me this output:

warden env-init --help

Environment Types:
  local               Declares the docker-compose version and labels the project
                      network allowing Warden to recognize it. Must be coupled with
                      per-project configuration. See documentation for details:
                      https://docs.warden.dev/environments/types.html#local

                      and rabbitmq services pre configured for Magento 2; on macOS

                      Due to the fact that Symfony uses  file too,
                      WEBROOT value of  is used by default

So everything within the markdown code enclosures ` gets executed. I added `ls -alh` into the text of env-init.help and when i enter the command again my current directory gets listed.

I see it as a security risk to execute the code samples in the help file. And as bug that i can't see them in the printed help text.
I use Ubuntu 20.04 and zsh.
