Need for more Node.js/JavaScript coverage in the recipes

How to test this PR?

• Start podman desktop pointing to a copy of the podman-desktop-extension-ai-lab with this PR (pnpm watch --extension-folder ../podman-desktop-extension-ai-lab/packages/backend from clone of podman-desktop project is the way I do it)
• Navigate to the Recipe Catalog under AI Lab (Might have to install AI Lab if it is not already)
• Select the Node.js RAG chatbot recipe
• Follow the standard steps to start the recipe
• Validate that you can get to the main page and chat/adding documents works as you would expect from the main page.

Could you please add values for languages and frameworks properties which have been added recently, and which will help the user filter the catalog (you can get examples of values in the PR #2354

As we added Granite 3.1 as the default model for several recipes, can you do it here and add the fields as @feloy mentioned

Thanks
