Comment placement on GitHub is sometimes wrong

[scastlara]

Describe the bug
Sometimes, the comment on GitHub are not well placed. We used to have that problem before, but in that case it was due to the AI not selecting the correct lines. Now it seems different to me.

To Reproduce
No reproducer, but I have an example:

#30 (comment)

Expected behavior
The comment should be placed correctly.

Additional context

We need to check:

• Is the relative line number correctly calculated?
• Is the git diff correctly passed to the AI?
• Given the relative number there, are we really using the GitHub API correctly?

ModifiedLine(
                    line="            rich.print(terminal_formatter.format_review_comments_section(review.review_response.comments))",
                    line_number=152,
                    relative_line_number=9,
                    modification_type="removed",
                ),
                ModifiedLine(
                    line="            printer(formatter.format_review_comments_section(review.review_response.comments))",
                    line_number=158,
                    relative_line_number=10,
                    modification_type="added",
                ),

This is what we parse from the git diff, which I think is simply wrong 🙃 The relative line number is not correct.
