Closes #207

Description

• Add extensions parameter to automatically install the VS-Code extensions
• Add settings parameter for workspace-specific configuration
• Create setup.sh script to install extensions & settings management
• Add validation for extension format (publisher.extension-name)
• Update test to the coverage for new features
• Support graceful fallback when VS Code CLI is unavailable

This pull request introduces functionality to automate the setup of Visual Studio Code (VS Code) workspaces, including the installation of extensions and configuration of workspace settings. It adds new Terraform variables and resources, a setup script, and corresponding tests to ensure proper behavior.

Terraform Module Enhancements:

• Added extensions, settings, and install_extensions variables to allow users to specify VS Code extensions, workspace settings, and control automatic installation behavior. Validation ensures proper formatting for extensions. (registry/coder/modules/vscode-desktop/main.tf, registry/coder/modules/vscode-desktop/main.tfR41-R85)
• Introduced a coder_script resource that dynamically creates a setup script to install extensions and configure settings when applicable. (registry/coder/modules/vscode-desktop/main.tf, registry/coder/modules/vscode-desktop/main.tfR41-R85)

Setup Script:

• Implemented a comprehensive Bash script (setup.sh) to handle the installation of extensions, configuration of workspace settings, and creation of extension recommendations. The script includes robust error handling, logging, and validation mechanisms. (registry/coder/modules/vscode-desktop/setup.sh, registry/coder/modules/vscode-desktop/setup.shR1-R267)

Documentation Updates:

• Updated the README.md to include examples for auto-installing extensions, configuring settings, and disabling automatic installation. (registry/coder/modules/vscode-desktop/README.md, registry/coder/modules/vscode-desktop/README.mdR38-R77)

Testing:

• Added multiple test cases to validate the behavior of the setup script, including scenarios with extensions, settings, and the install_extensions flag. (registry/coder/modules/vscode-desktop/main.test.ts, registry/coder/modules/vscode-desktop/main.test.tsR89-R143)
