Streaming configuration - updates are not propagated

[tomhreb]

Expected Behavior

Using IOptionsMonitor I can receive updates from dapr configuration store.

Actual Behavior

I am not receiving updates from the configuration store.

Steps to Reproduce the Problem

This can be reproduced using minimal api app

Project file

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Extensions.Hosting" Version="3.1.8" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\src\Dapr.Extensions.Configuration\Dapr.Extensions.Configuration.csproj" />
  </ItemGroup>

</Project>

Program.cs

using Dapr.Client;
using Dapr.Extensions.Configuration;
using Microsoft.Extensions.Options;

var client = new DaprClientBuilder().Build();
var builder = WebApplication.CreateBuilder(args);
var services = builder.Services;
var configuration = builder.Configuration;

configuration.AddDaprConfigurationStore("redisConfig", new List<string> { "version" }, client, TimeSpan.FromSeconds(20));
configuration.AddStreamingDaprConfigurationStore("redisConfig", new List<string> { "version" }, client, TimeSpan.FromSeconds(20));

services.Configure<MyOptions>(builder.Configuration);
var app = builder.Build();

app.MapGet("/", context =>
{
    var config = context.RequestServices.GetRequiredService<IOptionsMonitor<MyOptions>>();

    return context.Response.WriteAsJsonAsync(config.CurrentValue.Version);
});

app.Run();

class MyOptions
{
    public string Version { get; set; }
}

By periodically quering this endpoint while updating the key in redis, the response shculd report updated value, which is not happening and the first value is reported.

EDIT: I've found the root cause and created #935

RELEASE NOTE: Fixed `DaprConfigurationStoreProvider` not applying case-insensitive configuration updates correctly.
