[v-amyang]

OS: Win11 x64
Build Version: 0.12.8-alpha.0
VS Code Version: Version: 1.137.0

Repro Steps:

1. Create and scaffold an Azure project
2. Complete the Local Development phase
3. Start the Deployment workflow
4. Select an Azure subscription for deployment
5. Wait for the Azure Deployment Plan page to be generated
6. Review the plan before approving it

Expect:
The Azure Deployment Plan should display the selected Azure subscription name and subscription ID, so the customer can clearly verify the deployment target before approving the plan.
For example:

• Subscription: AzCode2607
• Subscription ID: 7ac60bd1-23ed-4537-9243-5c730308d661

Actual:
The Azure Deployment Plan displays the location, environment, estimated cost, prerequisites, and planned Azure resources.
However, the selected Azure subscription name and subscription ID are not displayed on the plan page
