pythongh-134690: Removed deprecated `codetype.co_lnotab`

I had a PR for that somewhere but Irit wasn't very convinced by the removal at that time: #119665 and #119664.

We're six weeks out from the 3.15 feature freeze, do we want to do this for 3.15 or update the docs to aim for 3.16?

In November 2024, we bumped "may be removed in 3.14" to "may be removed in 3.15":

gh-101865: Docs: Keep co_lnotab deprecation for at least 3.14 #126392

At that time, pytorch and huggingface were called out as still using it, but they've now been updated:

I've updated #134691
I am always in favor of removing stuff when possible :)
