Add/update badges for Google Colab and Lightning Studio

[sugatoray]

Added/updated badges for open-in-colab and open-in-lightning-studio:

• [x] formatted badges to reuse the same link for colab
• [x] added Lightning Studio badges
  • [x] for whole repo (at the top)
  • [x] for individual example notebooks (next to colab badges)

Lightning Studio provides a managed service and free compute alike Google Colab. Offers both VS Code and Jupyter Notebook in-browser. For individuals it provides free GPU, CPU and storage (free credits renew monthly). Since the managed service gets the entire repo setup in seconds, it could be useful to provide a link to Lightning Studio alongside Google Colab.
