test: another set of updates related to line terminator handling

This group of updates is similar to the last one, but they call out the
fact that while the change is an improvement, it does still seem to be a
little buggy.

As one example, previously we would have this:

       |
     1 | / from __future__ import annotations
     2 | |
     3 | | from typing import Any
     4 | |
     5 | | from requests import Session
     6 | |
     7 | | from my_first_party import my_first_party_object
     8 | |
     9 | | from . import my_local_folder_object
    10 | |
    11 | |
    12 | |
    13 | | class Thing(object):
       | |_^ I001
    14 |     name: str
    15 |     def __init__(self, name: str):
       |
       = help: Organize imports

And now here's what it looks like after:

       |
     1 | / from __future__ import annotations
     2 | |
     3 | | from typing import Any
     4 | |
     5 | | from requests import Session
     6 | |
     7 | | from my_first_party import my_first_party_object
     8 | |
     9 | | from . import my_local_folder_object
    10 | |
    11 | |
    12 | |
       | |__^ Organize imports
    13 |   class Thing(object):
    14 |     name: str
    15 |     def __init__(self, name: str):
       |
       = help: Organize imports

So at least now, the diagnostic is not pointing to a completely
unrelated thing (`class Thing`), but it's still not quite pointing to
the imports directly. And the `^` is a bit offset. After looking at
some examples more closely, I think this is probably more of a bug
with how we're generating offsets, since we are actually pointing to
a location that is a few empty lines _below_ the last import. And
`annotate-snippets` is rendering that part correctly. However, the
offset from the left (the `^` is pointing at `r` instead of `f` or even
at the end of `from . import my_local_folder_object`) appears to be a
problem with `annotate-snippets` itself.

We accept this under the reasoning that it's an improvement, albeit not
perfect.
