ServiceBusTrigger ignoring the DefaultAzureCredentialOptions set in DefaultAzureCredentials

### Description

My function app is developed using .NET 8 with isolated worker process. We have a service bus trigger function.

In my local development, i wanted to turn off managed identity based authentication and instead use either visual studio or visual studio credentials

I tried to turn off using the DI with the below code

```
services.AddAzureClients(clientBuilder =>
{
var options = new DefaultAzureCredentialOptions
{
ExcludeManagedIdentityCredential = true
};

clientBuilder.UseCredential(new DefaultAzureCredential(options));
});
```

But ServiceBus trigger is not using the above options and still tried to authenticate using managed identity credentials

Could you please let me how do we turn off Managed identity authentication for service bus trigger

The version am using for Microsoft.Azure.Functions.Worker.Extensions.ServiceBus is 5.17.0

### Steps to reproduce

Refer the description

The payload names no repository files, tests, or entry points. Start by reproducing the .NET 8 isolated-worker ServiceBus trigger with Microsoft.Azure.Functions.Worker.Extensions.ServiceBus 5.17.0 and the shown DefaultAzureCredentialOptions configuration; done means the trigger honors the managed-identity exclusion or the supported configuration path is documented.
