Add Getting Started walkthrough to VS Code extension

[adamint]

Description

Adds a Getting Started walkthrough to the Aspire VS Code extension. The walkthrough guides new users through installing the CLI, creating a project, running their app, exploring the dashboard, and next steps — all from within VS Code.

What's included

6 walkthrough steps:

1. Welcome to Aspire — overview of key benefits, how it works, polyglot support
2. Install the Aspire CLI — platform-specific install commands (stable + daily) with clickable terminal links
3. Create a new project — links to the Aspire: New Aspire Project command, explains the apphost and template structure
4. Run your app — run/debug via extension commands, dashboard screenshot, link to dashboard overview
5. Explore the dashboard — resources, endpoints, logs, traces, metrics, health monitoring
6. Next steps — integrations, publish/deploy, learning resources

3 new commands for the install step:

• aspire-vscode.installCliStable — runs the stable CLI install script in a terminal
• aspire-vscode.installCliDaily — runs the daily/preview CLI install script in a terminal
• aspire-vscode.verifyCliInstalled — runs aspire --version to verify installation

All strings are localized via package.nls.json. Markdown panels include clickable command: links to run extension commands directly.

This is good for now but when we ship 13.2 maybe replace it w whatever typescript template we ship?
