Does this issue occur when all extensions are disabled?: No (the feature is in the Copilot Chat extension)

• VS Code Version: 1.103.2
• OS Version: Windows

@joelverhagen (me) will provide a fix for this.

The schema for server.json has been update:
https://github.com/modelcontextprotocol/registry/blob/main/docs/reference/server-json/server.schema.json

The code for assisted NuGet MCP install uses the old schema:
https://github.com/microsoft/vscode-copilot-chat/blob/bb62f6f6367e48879506c1989ddae6fe5e5c3a26/src/extension/mcp/vscode-node/nuget.ts#L288

This needs to be fixed to the latest schema.
