Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Building a new Blazor app with auto interactivity prompted by --help page returns missing symbol in resulting project.

 -int, --interactivity <None|Server|...>  Chooses which interactive render mode to use for interactive components
                                           Type: choice
                                             None         No interactivity (static server rendering only)
                                             Server       Runs on the server
                                             WebAssembly  Runs in the browser using WebAssembly
                                             Auto         Uses Server while downloading WebAssembly assets, then uses
                                           WebAssembly
                                           Default: Server

Expected Behavior

For the render mode attribute to correctly work.

Steps To Reproduce

dotnet new blazor --interactivity auto

In the Client -> Counter.razor page -> @rendermode InteractiveAuto -> “Cannot resolve symbol ‘rendermode’”

Exceptions (if any)

Cannot resolve symbol ‘rendermode’
