[jupyterbook-latex] no input/output labels for python-cell

[shlff]

Hi @AakashGfude and @mmcky , the first issue/difference between PDFs generated by rst and myst is that

• there is no input/output labels for python-cell of PDFs generated by myst files.

For example, please see here (left: PDFs generated by rst, right: PDFs generated by myst):

thanks @shlff that is largely stylistic and something we can add it as an improvement later on.

Thanks @mmcky .

This difference still exists, but it may not be an issue. I will leave it to you and @jstac to decide which style we should adopt.
