vimdiff: clarify the sigil used for marking the buffer to save

The original documentation from 7b5cf8be18 (vimdiff: add tool documentation, 2022-03-30) mistakenly described the marker as an asterisk, which is the character "*". The code and examples have always looked for an arobase ("@"). Signed-off-by: D.

88 When `MERGED` is not present in the layout, you must "mark" one of the
89 -buffers with an asterisk. That will become the buffer you need to edit and
89 +buffers with an arobase (`@`). That will become the buffer you need to edit and
90 save after resolving the conflicts.
