Pre-install VS Code extensions in desktop VS Code module

[matifali]

Extend the VS Code desktop module to automatically install the specified extensions and apply settings.

• Should accept the extension list as a parameter
• Should accept settings as input
• Should install the extension for the remote host
• Extend the existing VSCode Desktop module with this new feature

Note

When a user connects to a Coder workspace for the first time, the extension and settings should be pre-installed and pre-applied.

/attempt #207

My appraoch it to Add an extra extensions parameter that accepts a list of extension IDs. Create a new run.sh script that uses code --install-extension to install each extension during VM provisioning after VS Code setup. Include basic error handling and ensure proper user context for persistent installations.
