Replace hardcoded NuGet package versions with NuGet Package Manager guidance in Walkthrough 2

[Copilot]

Updated Task 1 (part 3) in 02-ImageProcessingAndStorageEvents.md to replace outdated hardcoded package versions with comprehensive NuGet Package Manager instructions.

Problem

The walkthrough documentation contained a hardcoded XML snippet with specific package versions that could become outdated over time:

<ItemGroup>
    <PackageReference Include="Azure.Messaging.ServiceBus" Version="7.15.0" />
    <PackageReference Include="CsvHelper" Version="30.0.1" />
    <!-- ... more packages with hardcoded versions ... -->
</ItemGroup>

This approach led to potential issues:

• Packages may have received version updates or name changes
• Copy-pasting outdated dependencies could cause errors
• Problems during GitHub Actions pipeline setup in Task 4

Solution

Replaced the hardcoded XML with step-by-step NuGet Package Manager instructions for all 10 required packages:

• Azure.Messaging.ServiceBus
• CsvHelper
• Microsoft.Azure.CognitiveServices.Vision.ComputerVision
• Microsoft.Azure.Cosmos
• Microsoft.Azure.Functions.Extensions
• Microsoft.Azure.WebJobs.Extensions.EventGrid (with specific search guidance)
• Microsoft.Azure.WebJobs.Extensions.Storage
• Microsoft.Extensions.DependencyInjection
• Microsoft.NET.Sdk.Functions
• Polly

Each package now includes clear instructions:

1. Open NuGet Package Manager
2. Search for the package name
3. Install the latest stable version

Benefits

• Always uses latest package versions
• Prevents version compatibility issues
• Reduces errors during GitHub Actions pipeline setup
• Follows recommended Azure development practices
• Maintains workshop compatibility with .NET 6 LTS

Fixes #13.

@copilot can we update this to .NET 8 instead of .NET 6?

[Copilot]

Updated all .NET 6 references to .NET 8 in the ImageProcessing walkthrough, including the NuGet package guidance, SDK download link, and Azure Function App deployment instructions. Commit 81432cc

@copilot Can you take a look and see if we can update these instructions to reflect .NET 8 and isolated workers in the function app (might need to change the packages to map to the isolated versions?)

Can we remove this and utilize .NET 8 with isolated workers for the function app?

[Copilot]

Removed the note about isolated functions not being tested and updated the entire walkthrough to use .NET 8 isolated worker functions with proper packages and configuration. Commit 23bb75a

Updated the instructions to use .NET 8 isolated worker Azure Functions with proper package references and code examples. Replaced all WebJobs packages with their isolated worker equivalents and added Program.cs setup guidance. Commit 23bb75a
