[AspNetCore] Support new error code for dev-certs --checkpr-support-dotnet-broken-certs

Due to the issue we found with 3.1 Preview2 on notarization, the .NET Core
team have added a new error code to detect that situation, so VSMac needs
to take it into account and run "dev-certs https --trust" as with other
known error codes, which should fix the issue.
