aspire-starter Sample not running in aspire 9.5.1 (missing dcp.exe in nuget package)

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

dcp.exe is missing in nuget package **aspire.hosting.orchestration.win-x86** Version 9.5.1

### Expected Behavior

dcp.exe is required for aspire. The sample should run without any errors.

### Steps To Reproduce

`dotnet new install Aspire.ProjectTemplates --force`
`dotnet new aspire-starter --output AspireSample`
`dotnet dev-certs https --trust`
`dotnet run --project AspireSample/AspireSample.AppHost`

I get this output:

### Anything else?

_No response_

Start with Aspire.Hosting/Dcp/DcpDependencyCheck.cs at line 47 and inspect how the aspire.hosting.orchestration.win-x86 package is produced, especially its tools directory. Reproduce with the listed Aspire template and dotnet run commands on Windows, then verify that the 9.5.1 package contains dcp.exe and the AspireSample.AppHost starts successfully.
