docs(upstream): mark stevearc#707 as duplicate of #117

Problem: Issue stevearc#707 (move file/dir into new dir by renaming) was listed
as `open` despite being identical to #117. The associated draft PR stevearc#708
is already tracked separately in the PRs table.

Solution: Update status to `duplicate of #117`.
