F# host: Could not find an implementation for interface OrleansDashboard.IDashboardGrain - C# host ok

Unable to host silo in F# console project. C# console project works fine. Please see attached minimal repo.

[FsGrains (2).zip](https://github.com/dotnet/orleans/files/10267813/FsGrains.2.zip)

Need to host in F# due to other F# frameworks (e.g. for web dev) required for the application.

Issue is with the 7.x version. This was not an issue with the 3.x.x version of Orleans.

F# hosting works if 'UseDashboard' is commented out.

Error seen:
```

Reproduce the failure using the attached FsGrains minimal repository, comparing the F# and C# console hosts with UseDashboard enabled and disabled. Start from OrleansDashboard.Dashboard.ActivateDashboardGrainAsync and the GrainInterfaceTypeToGrainTypeResolver.GetGrainType stack trace; done means the F# silo starts with UseDashboard enabled without the missing-implementation error.
