📚 Description

Added a preset azure-functions-streaming which adds support for the Azure Functions V4 runtime with HTTP Streaming enabled. This allows applications (like Solid Start) that require HTTP Streaming to now work properly on Azure Functions.

I also upgraded the @azure/functions package to the latest version, which is required to support this functionality.

📝 Checklist

• I have updated the documentation accordingly.

To do: Update regular azure-function preset to v4

Thanks for working on this dear Sacha. For now i have marked it as draft mainly to see if we can avoid new preset but instead add functionality to the main azure-functions (worst case via a runtime flag)

If you like to work and help on v4 support, feel free to open a new PR. Using new compatibility date system we can adopt it progressively (see netlify for reference)
