docs/for-each-ref: update pointer to color syntax

The documentation for the %(color) placeholder refers to the color.branch.* config for more details. But those details moved to their own section in b92c1a28f (Documentation/config.txt: describe 'color' value type in the "Values" section, 2015-03-03). Let's update our pointer. We can steal the text from 30cfe72d3 (pretty: fix document link for color specification, 2016-10-11), which fixed the same problem in a different place. While we're at it, let's give an example, which makes the syntax much more clear than just the text. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
