documentation: git-update-index: add --show-index-version to synopsis

In 606e088d5d (update-index: add --show-index-version, 2023-09-12), we added the new '--show-index-version' option to 'git-update-index' and documented it, but forgot to add it to the synopsis section. Add '--show-index-version' to the synopsis of 'git-update-index'. Signed-off-by: Dov Murik <dov.murik@linux.dev> Signed-off-by: Junio C Hamano <gitster@pobox.com>
