Summary

📝🛠️🚀

Improved the Helm tutorial by fixing the tabbed section for cloning and opening the sample code. This change affects the file helm/index.md.

We're sailing on the helm of the code, me hearties
We're fixing up the tabs and the docs, me hearties
We're making it easy for the learners to clone
Heave away, haul away, on the count of three

Walkthrough

• Move the code block for cloning and opening the sample code inside a tabbed section to allow users to choose between using a codespace or a local machine (link). This improves the user experience and consistency with other tutorials in docs/content/tutorials/helm/index.md.
