[microsoft/vscode] Install in SSH fails when `CachedExtensionVSIXs` directory does not exist

### ROOT CAUSE The `CachedExtensionVSIXs` directory is not created before the installation process attempts to access it, causing the `Install in SSH` functionality to fail when this directory doesn't exist. ### CODE FIX To fix the issue, we need to ensure the `CachedExtensionVSIXs` directory is created if it doesn't exist before attempting to use it. Here's the modified code: ```javascript const cachedExtensionVSIXsDir = path.join(extensionDir, 'CachedExtensionVSIXs'); // Check if the directory exists and create it if it doesn't if (!fs.existsSync(cachedExtensionVSIXsDir)) { fs.mkdirSync(cachedExtensionVSIXsDir, { recursive: true }); } // Continue with the installation process using the directory ``` This fix adds a check to create the directory if it's missing, preventing the failure during the `Install in SSH` process.
