Update cat2cloud notebook code

[lshaw8317]

For next release of blosc2 we can change the code in the notebooks since the wheels branch will have a latest.txt file. hence the followign should install blosc2

   # URL of the latest.txt file in GitHub Pages
    latest_url = "https://Blosc.github.io/blosc2/wheels/latest.txt"
    # Fetch wheel name
    wheel_name = requests.get(latest_url).text.strip()
    # Install the wheel dynamically
    wheel_url = f"https://Blosc.github.io/blosc2/wheels/{wheel_name}"
    await micropip.install(wheel_url)
    print(f"Installed {wheel_name} successfully!")
