What does this MR do and why?
Add a known issue in import_export.md.
During the import/export process, only the most recent merge request diffs will be retained.
After multiple verifications and source code review, I found that this is a reproducible problem. In the exported data, the type of the merge_request_diff field is a dictionary rather than an array. Therefore, when there are multiple merge_request_diff, only one of them will be taken.
