feat: enhance Excel cell writer tool with JSON updates and improved error handling

- Removed debug print statements from `excel-cell-editor.py` and `excel-cell-writer.py`.
- Added JSON parsing for updates in `excel-cell-writer.py`, allowing for string input to be processed as JSON.
- Implemented error handling for invalid updates format and JSON parsing errors in `excel-cell-writer.py`.
- Updated `excel-cell-writer.yaml` to include a new parameter for cell updates, specifying the format for inputting cell references and their new values.
