New Feature: Run Cells Above

This pull request introduces a new feature run_cells_above to the NotebookNavigator plugin. This function allows users to execute all code cells above the current cell, which is similar to functionality seen in tools like Jupyter notebooks.

Implementation:

• The function calculates the current cell's position and executes each cell above it.
• Utilizes the existing infrastructure for running cells but adds logic to determine the scope of execution dynamically based on the cursor's position.

Usage:

Users can invoke this function via a command or keybinding in Neovim. Example usage might be via a mapped key in normal mode, such as below

   ...
    keys = {
      ...
      { "[e", function() require("notebook-navigator").run_cells_above "" end },
    },
   ...

Request for Feedback:

Please review the implementation details and functionality. I am open to suggestions for improvements or additional scenarios that should be considered.

Looking forward to your feedback and hoping for integration into the main project!
