fix: split diff file to allow process_diff unit test to pass

The diff file has a couple of hunks which for
some unknown reason have parsing issues which
result in the wrong line being detected for where
the TODO is. This causes the issue URL insertion
to fail. That's its own issue that should be
investigated, but in order to allow the process_diff
unit test to pass, the diff file is being split
into two to isolate the trouble-causing hunks.
