Bad docstring for if

[MartinPuda]

As you can see here: https://clojuredocs.org/clojure.core/if, current docstring for if is "Evaluates test.", instead of expected:

if
  (if test then else?)
Special Form
  Evaluates test. If not the singular values nil or false,
  evaluates and yields then, otherwise, evaluates and yields else. If
  else is not supplied it defaults to nil.
