CLI searching for templates failed with JsonReaderException: 'W' is an invalid start of a value. and stack

[danmoseley]

I assume we just got a bad response from the server. Need to catch JsonReaderException. Unless @mitchdenny philosophically should this be a bug aginst the dotnet CLI?

C:\git\aspire>C:\git\aspire\artifacts\bin\Aspire.Cli\Debug\net8.0\aspire.exe new
Enter the project name: (aspire): xx
Enter the output path: (./x): ./xx
