Upgrading "aspire" workload causes builds to fail until Visual Studio is restarted

### Describe the bug

I had a solution open in Visual Studio 2022 when I ran "dotnet workload update" on the command line, which upgraded the "aspire" workload from 8.0.1 to 8.0.2. After this, when I tried to build a project in Visual Studio, it failed with an error saying that Microsoft.NET.Sdk.ImportWorkloads.props was not able to import AutoImport.props from version 8.0.1 of Aspire.

Nothing in the solution references Aspire.

I tried to restore NuGet packages again in Visual Studio, and also with `nuget restore -force -forceEvaluate`, but it didn't help. I then restarted Visual Studio, and the build started working again.

The problem seems to be that Microsoft.NET.Sdk.WorkloadMSBuildSdkResolver.CachingWorkloadResolver assumes Visual Studio will be restarted when workloads are updated. The "dotnet workload update" command did not restart Visual Studio and did not tell me to restart it.

### To Reproduce

I can't reproduce it now, as I can't figure out how to reinstall version 8.0.1 of the "aspire" workload for .NET SDK 8.

This may be related to me having installed .NET SDK 8 and the "aspire" workload long before I installed Visual Studio 2022.

### Exceptions (if any)

I lost the error message.

### Further technical details

As I've uninstalled and reinstalled various SDK versions and workloads while trying to reproduce the error, the following output of `dotnet --info` no longer matches what it would have been when the error occurred. In particular, I don't think the "Installation Source" of "aspire" would have been VS.
