Add cell_execute_result to TestbookNotebookClient

[fcollonval]

Similarly to cell_output_text,

testbook/testbook/client.py

Lines 137 to 146 in 957cc4d

	def cell_output_text(self, cell) -> str:
	"""
	Return cell text output
	"""
	cell_index = cell
	if isinstance(cell, str):
	cell_index = self._cell_index(cell)
	return self._output_text(self.nb['cells'][cell_index])

it would be nice to have a method cell_execute_result.

What do you think?

Yes, for sure. However, there is an internal static method - TestbookNotebookClient._execute_result which does the job.

Perhaps we could implement a new function cell_execute_result which would internally call _execute_result. Let me know if you would like to take this up @fcollonval 👍

Sure I'll push a PR next week.
