[Minimal APIs] async handlers with single `HttpContext` parameter are not working

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

It seems that issue described in https://github.com/dotnet/aspnetcore/issues/39956 was not fixed but even got worse - Minimal APIs handler with single param of type `HttpContext` results in empty response.

```csharp
app.MapPost("testpost_works", async (HttpContext context, CancellationToken ct) => await Task.FromResult(context.Request.Method + " response"));
app.MapPost("testpost_fails", Handler);
app.MapGet("testget_works", async (HttpContext context, CancellationToken ct) => await Task.FromResult(context.Request.Method + " response"));
app.MapGet("testget_fails1", async (HttpContext context) => await Task.FromResult(context.Request.Method + " response"));
app.MapGet("testget_fails2", Handler);

async Task Handler(HttpContext context) => await Task.FromResult(context.Request.Method + "response");
```

Endpoints suffixed `fails` return empty result while others return "VERB response"

In addition only "works" endpoints are recognized by swagger:


### Expected Behavior

All endpoints return "VERB response"

### Steps To Reproduce

Use Minimal APIs defined above.

### Exceptions (if any)

_No response_
