dotnet watch crashes net10.0 Azure Functions project with FileNotFoundException

### Describe the bug

Running an Azure Functions (isolated worker) project targeting net10.0 under `dotnet watch` crashes immediately on startup with the `System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=10.0.0.0` exception.

The same project running against net8 works fine.

### Steps to reproduce

1. Create an Azure Functions isolated-worker project targeting net10.0.
1. Have Azure Functions Core Tools installed, where func.exe runs on .NET 8 (func --version: ).
1. Run the project with `dotnet watch`
1. Observe an immediate exception

### Expected behavior

`dotnet watch` runs without exception for net10 function app.

### Actual behavior

`dotnet watch` fails with an exception:
```
Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.
File name: 'System.Runtime, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

at System.StartupHookProvider.CallStartupHook(StartupHookNameOrPath startupHook)
at System.StartupHookProvider.ProcessStartupHooks(String diagnosticStartupHooks)
```

### Is this a regression?

When changing the target framework to net8, `dotnet watch` seems to be working as expected.

### Are there any workarounds?

_Just a note:_
I first encountered this when running `aspire run` with `"defaultWatchEnabled": "true"` - my Azure Functions services failed to start with that setting on. I narrowed the cause down to the dotnet watch command.
