StreamOutputFormatter doesn't react to client disconnect

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

We have a controller action returning a stream and had a HTTP request hanging here after the client had already disconnected:

https://github.com/dotnet/aspnetcore/blob/e742462cfbe457e627ad95a9d47e90d8372e43cb/src/Mvc/Mvc.Core/src/Formatters/StreamOutputFormatter.cs#L40

I assume this is missing `context.HttpContext.RequestAborted` as a `cancellationToken`.

I could make a PR (or feel free to assign it to Copilot).

### Expected Behavior

Request should abort when client disconnects.

### Steps To Reproduce

_No response_

### Exceptions (if any)

### .NET Version
