Revert "Support relative line number on wrapped lines (#39268)" (#41450)

Closes #41422

This completely broke line numbering as described in the linked issue
and scrolling up does not have the correct numbers any more.

Release Notes:

- NOTE: The `relative_line_numbers` change
(https://github.com/zed-industries/zed/pull/39268) was reverted and did
not make the release cut!
