[PATCH 3/3] githooks.txt: Minor improvements to the grammar & phrasing

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change:

 * Sentences that needed "the" or "a" to either add those or change them
   so they don't need them.

 * The little tangent about "You can use this to do X (if your project
   wants to do X)" can just be shortened to "e.g. if you want to do X".

 * s/parameter/parameters/ when the plural made more sense.

Most of this goes all the way back to the initial introduction of
hooks.txt in v0.99.5-76-g6d35cc7 by Junio.
