[PATCH] config/core.txt: fix minor issues for `core.sparseCheckoutCone`

["Martin Ågren" <martin.agren@gmail.com>]

The sparse checkout feature can be used in "cone mode" or "non-cone
mode". In this one instance in the documentation, we refer to the latter
as "non cone mode" with whitespace rather than a hyphen. Align this with
the rest of our documentation.

A few words later in the same paragraph, there's mention of "a more
flexible patterns". Drop that leading "a" to fix the grammar.

 BTW, Elijah, it seems like you've recently started using different
 e-mail addresses, even within the same series [1]. Not sure if that's
 intentional or not? I decided to cc the one you've used by far the most
 rather than spamming all of your accounts.
