Fix comments: co_lnotab to co_lines

[cclauss]

In 34786db the code was changed, but the comment was not.

DeprecationWarning: co_lnotab is deprecated, use co_lines instead.

lnotab still exists in the codebase, but I do not think those files are on the critical path.

Thanks! BTW, how did you find the discrepancy? (And I should move the whole lab/ directory out of this repo....)
