[lecture_comparison]_no_labels_``In``&``Out``_for_code_cells&its_outputs_in_myst

[shlff]

Hi @mmcky , I find

• there are no labels In&Out for code cells and its outputs in MYST versions, but we do have those labels in RST versions.

For example, in lecture heavy_tails (left: MYST, right: RST),

Do you think it is an issue?

This would be changed in quantecon-book-theme

They could be added if we want them back.
