`code.co_linetable` is undocumented

[brettcannon]

https://peps.python.org/pep-0626/#the-co-linetable-attribute says it's an implementation detail, but I had to find that reference via the changelog linking to the PEP to find out what the attribute is for.

@brettcannon Can I assign this issue to the new contributor at PyCon KR sprint? (next week)

If it's an implementation detail, do we even want to document it?

I wasn't planning to fix it, so I'm fine with that!

If it's an implementation detail, do we even want to document it?

I think so because it isn't prefixed as private, all other attributes are documented, and attributes don't have a docstring to just say, "this is an implementation detail". And honestly the docs can just say it's an implementation detail and move on without much work.
