test: update snapshot with fixed annotation but carets include whitespace

I separated out this snapshot update since the string of `^` including
whitespace looked a little odd. I investigated this one specifically,
and indeed, our span in this case is telling `annotate-snippets` to
point at the whitespace. So this is `annotate-snippets` doing what it's
told with a mildly sub-optimal span.

For clarity, the before rendering is:

    skip.py:34:1: I001 [*] Import block is un-sorted or un-formatted
       |
    32 |       import sys; import os  # isort:skip
    33 |       import sys; import os  # isort:skip  # isort:skip
    34 | /     import sys; import os
       |
       = help: Organize imports

And now after is:

    skip.py:34:1: I001 [*] Import block is un-sorted or un-formatted
       |
    32 |     import sys; import os  # isort:skip
    33 |     import sys; import os  # isort:skip  # isort:skip
    34 |     import sys; import os
       | ^^^^^^^^^^^^^^^^^^^^^^^^^ I001
       |
       = help: Organize imports

This is a clear bug fix since it adds in the `I001` annotation, even
though the carets look a little funny by including the whitespace
preceding `import sys; import os`.
