[PATCH] docs/git-gc: fix minor rendering issue

["SZEDER Gábor" <szeder.dev@gmail.com>]

An unwanted single quote character in the paragraph documenting the
'gc.aggressiveWindow' config variable prevented the name of that
config variable from being rendered correctly, ever since that piece
of docs was added in 0d7566a5ba (Add --aggressive option to 'git gc',
2007-05-09).

Remove that single quote.
