Fix API version for databricks-workspace-with-vnet-injection to support existing workspace VNet updates

[Copilot]

Updates the Azure Databricks workspace template API version to support VNet injection on existing workspaces.

Problem

The current template fails when trying to apply VNet injection to existing Databricks workspaces with the following error:

VirtualNetworkIdChangeNotAllowed: Updating required Virtual Network from  to /subscriptions/.../providers/Microsoft.Network/virtualNetworks/vnet_for_injection is allowed only in api-version 2025-02-01-preview or beyond

Solution

Updated the Microsoft.Databricks/workspaces API version from 2024-05-01 to 2025-02-01-preview to support VNet updates on existing workspaces.

Changes Made

• Updated API version in main.bicep from 2024-05-01 to 2025-02-01-preview
• Rebuilt azuredeploy.json from the updated Bicep template
• Updated metadata.json with current date

Testing

• ✅ Template syntax validation passes
• ✅ JSON structure validation passes
• ✅ Deployment file validation passes

This change maintains backward compatibility for new workspace creation while enabling the VNet injection scenario described in the Azure Databricks VNet injection documentation.

Fixes #14515.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• aka.ms
  • Triggering command: bicep build main.bicep --outfile azuredeploy.json (dns block)
  • Triggering command: bicep build main.bicep --outfile /tmp/test-output.json (dns block)
  • Triggering command: pwsh -NoProfile -Command try { & './test/ci-scripts/Validate-Metadata.ps1' './quickstarts/microsoft.databricks/databricks-workspace-with-vnet-injection/metadata.json'; Write-Host 'Metadata validation passed' } catch { Write-Host 'Metadata validation failed:' /home/REDACTED/work/azure-quickstart-templates/azure-quickstart-templates.Exception.Message } (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to my firewall allow list
