docs/pretty-formats: mention commas in %(trailers) syntax

Commit 84ff053d47 (pretty.c: delimit "%(trailers)" arguments
with ",", 2017-10-01) switched the syntax of the trailers
placeholder, but forgot to update the documentation in
pretty-formats.txt.

There's no need to mention the old syntax; it was never in a
released version of Git.
