[PATCH] builtin/reflog.c: fix dry-run option short name

[Josh Brobst <josh@brob.st>]

The documentation for reflog states that the --dry-run option of the
expire and delete subcommands has a corresponding short name, -n.
However, 33d7bdd645 (builtin/reflog.c: use parse-options api for expire,
delete subcommands, 2022-01-06) did not include this short name in the
new options parsing.

Re-add the short name in the new dry-run option definitions.
