Support jumping to specific notebook cell via reference (e.g., file.ipynb:cell 38:13:5)

[mthiboust]

I’d like to request a feature to jump directly to a specific cell in a Jupyter notebook when clicking a reference like path/to/notebook/file.ipynb:cell 38:13:5 in VS Code, similar to how path/to/file.py:123 navigates to a line in a Python file.

Use Case:
When formating/linting notebooks, I receive references in the format file.ipynb:cell X:Y:Z (from ruff in my case), where X is the cell number, and Y:Z are line/column positions within the cell. Currently, I can open the notebook by clicking the file path, but I must manually navigate to the cell, which is time-consuming for notebooks with many cells.

Proposed Feature:
Enable Ctrl+click (or similar) on a reference like file.ipynb:cell 38:13:5 to:

• Open the notebook if not already open.
• Jump to cell 38 (1-based indexing).
• Optionally, focus on line 13, column 5 within the cell’s content, if feasible.

Support this in the editor, terminal, or other clickable contexts (e.g., Output panel).

I often think about this and would use it - I think in the past I noticed that some tools index only code cells
