diff-format.adoc: remove mention of diff-tree specific output

In the "Raw output format" section, we start by mentioning that 'git diff-tree' prints the hashes of what is being compared. This is only true in --stdin mode, and is already mentioned in the description of '--stdin' in git-diff-tree.adoc. Remove this sentence such that we only focus on the common output between diff-tree, diff-index, diff-files and Signed-off-by: Junio C Hamano <gitster@pobox.com>
