Tutorials: add Open in Studio badge

[adamjstewart]

Adds a new button to our tutorials to open them in the new Lightning Studio platform.

Based on https://lightning.ai/badge.

Still need to test, but I think this code organization is more clear in my mind.

I tested this and confirmed that:

1. The Google Colab badge still works
2. The new Lightning Studio badge works
3. All current tutorials work in Lightning Studio

I think this is finally ready for review.

One open question is which badge to put first, Colab or Studio. Some pros of each, based on my limited experience:

Colab

• Simpler interface (fewer controls)
• More popular
• More likely to already have a Google account
• Faster to attach compute and start running
• Greater stability (fewer bugs)
• Developed by Google (less likely to be abandoned in a year)

Studio

• More powerful (more controls)
• More reproducible (entire environment is saved)
• Clearer usage limits for free and paid plans
• Can clone an entire repo and run multiple tutorials consecutively without reinstalling pip dependencies
• Choose between VS Code or Jupyter interface
• Builtin terminal
• Develop in Studio and immediately push to git
• Developed by the same people who make lightning and torchmetrics, more PyTorch focused
• Not developed by Google (more likely to get support)

Overall, Colab is more beginner friendly, but Studio is clearly superior in every way for those with even a bit of experience. After only using it for 5 min, I already know I'll never use Colab again.

I'm curious what experiences others have had and which button they think should be listed first. Since TorchGeo and Lightning are both PyTorch-focused products, I'm leaning towards Lightning, but I'm also biased. Please only comment if you've used both Colab and Studio (sign up for a free account now and give it a try!).

Waiting on verification for my lightning account to test, but if it works for you then I'm good with it!

Opening the notebooks in lightning-studio also worked for me.
