Redis Connector failing when initialized as in sample

[HSven1611]

Describe the bug
When using the newly introduces redis connector as described in the quickstart it crashes when accessing the memory.

This is just a documentation issue as far as I see it.

To Reproduce
Steps to reproduce the behavior:

1. initialize redis connector as in sample
2. try to access memory

Exception:
Microsoft.Bot.Builder.Integration.AspNet.Core.IBotFrameworkHttpAdapter[0]
[OnTurnError] unhandled error : Cannot access a disposed object.
Object name: 'DELL5B70FK3(SE.Redis-v2.6.96.30123)'.
System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'DELL5B70FK3(SE.Redis-v2.6.96.30123)'.
at StackExchange.Redis.ConnectionMultiplexer.ExecuteAsyncImpl[T](Message message, ResultProcessor`1 processor, Object
[...]

I think it eventually disposes something the redis memory connector needs to work. In my application there is some time between initialization and usage as I'm waiting for some user input.

Fix
remove using before Connection multiplexer.

old:

using ConnectionMultiplexer connectionMultiplexer = await ConnectionMultiplexer.ConnectAsync("localhost:6379");

new:

ConnectionMultiplexer connectionMultiplexer = await ConnectionMultiplexer.ConnectAsync("localhost:6379");

Expected behavior
Should not crash and access the memory.

Desktop (please complete the following information):

• OS: Windows
• IDE: VS2022
• NuGet Package: Microsoft.SemanticKernel.Connectors.Memory.Redis
• NuGet Package version: 0.15.230609.2-preview

Additional context
Sample code in quick Start 2. seems broken

The document simply demonstrates how to use it quickly, similar to Example47_Redis.cs. In the application, ConnectionMultiplexer should typically be a singleton, and as a best practice, it should be disposed once done using. Additionally, when writing this README.md, I instinctively believe that users should first understand how to use ConnectionMultiplexer (StackExchange.Redis).
