doc: mention 'git show' defaults to HEAD

When 'git show' is called without any object it defaults to HEAD.  This
has been true since d4ed9793fd ("Simplify common default options setup
for built-in log family.", 2006-04-16).

The SYNOPSIS suggests that the object argument is required.  Clarify
that it is not required and note the default.
