Python tracebacks: skip first DefaultExecutor.execute_cell item

[yairchu]

Description

The traceback for any error in a Marimo Python cell starts with:

Traceback (most recent call last):
   File ".../site-packages/marimo/_runtime/executor.py", line 139, in execute_cell
    return eval(cell.last_expr, glbls)
  Cell marimo://<NOTEBOOK>#cell=<CELL>, line <LINE>, in <module>

As the first execute_cell traceback is always there it is not informative, and merely exposes a Marimo implementation details whereas the user would expect the cell to be the first traceback item

Suggested solution

Filter out the first traceback item of execute_cell
