Mac: dotnet dev-certs https --trust does not explain how to undo this

[migueldeicaza]

When you run this command, it does not say what actually is taking place, it leaves a critical element, which is needed later to undo this:

$ dotnet dev-certs https --trust
Trusting the HTTPS development certificate was requested. If the certificate is not already trusted we will run the following command:
'sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain <<certificate>>'
This command might prompt you for your password to install the certificate on the system keychain.

I could not figure out what certificate was added to my system, it took me a while to debug this as the actual certificate is replaced with the string <<certificate>> above.
