fix: init notebook execution on windows

[FilipPyrek]

Deepnote Cloud creates init notebooks with pre-defined bash script for installation of dependencies. The problem is that bash doesn't run on Windows by default.

The solution is to replace the pre-defined bash script with cross-platform python script.

Summary by CodeRabbit

• Bug Fixes

  • Improved cross-platform notebook initialization with enhanced Windows support.

• New Features

  • Added environment-specific initialization handling for different development environments.

BLU-5107 Change init notebook script in Deepnote cloud to be multiplatform

📝 Walkthrough

Walkthrough

Modified the init notebook runner to handle cross-platform compatibility. Added two new constants distinguishing Deepnote cloud and VSCode initialization block contents. When executing notebook blocks on Windows, the system detects if a block contains Deepnote cloud initialization content, replaces it with VSCode-compatible Python content, and proceeds with execution. This allows dependency installation to work on Windows in addition to Linux/macOS environments.

272-285: Code is correct; brittleness concern doesn't apply.

The exact string match is sound because DEEPNOTE_CLOUD_INIT_NOTEBOOK_BLOCK_CONTENT is a fixed constant from a single location, properly trimmed, with no competing bash-based init blocks in the codebase. The Windows-specific replacement logic is appropriate.
