When running blazor project via aspire.cli (not Aspire in VS, not separately), blazor.web.js 404s

### Is there an existing issue for this?

### Describe the bug

https://github.com/dotnet/aspnetcore/issues/64985

When trying to contribute to Wiremock.net I've noticed when the web-project that's part of their Aspire examples is run within the context of *Aspire CLI*, blazor fails due to requests for blazor.web.js failing with 404 (from kestrel).

When the project is run standalone it all works fine. When the project runs from VS (win) as startup aspire host project, it is fine.

### Expected Behavior

It should work.

### Steps To Reproduce

1. Clone https://github.com/petrroll/WireMock.Net/tree/petrhouska/update-aspire
2. Run (using aspire cli) `aspire run ./examples-Aspire/AspireApp1.AppHost/AspireApp1.AppHost.csproj`
3. Open the webfrontend portal
4. Observe 404 error for `blazor.web.js` (and generally broken blazor experience on /weather

### Exceptions (if any)

GET https://localhost:7263/_framework/blazor.web.js net::ERR_ABORTED 404 (Not Found)
Responder is Kestrel, so there's no caching shenanigans
