[Minimal API] Route, Query and Header parameter names are ignored when using WithOpenApi extension method

[marcominerva]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

Let's consider the following endpoint, in which every argument has been renamed with the corresponding attribute:

app.MapGet("/api/{id:guid}/search", ([FromRoute(Name = "id")] Guid searchId, 
    [FromQuery(Name = "q")] string searchText, [FromHeader(Name = "x-version")] string version) =>
{
    return TypedResults.NoContent();
});

Resulting OpenAPI documentation will show the correct names:

However, if I just add the WithOpenApi extension method, then parameter names are ignored, so the generated documentation will become incorrect:

Expected Behavior

Parameter names should be taken into account even when using the WithOpenApi extension method.
