revset: fix documentation for 'remote()' predicate

current documentation for 'remote()' predicate is wrong about
specification of parameters.

there are 3 patterns:

  # of
  param:  id:              remote:
  - 0     current branch   "defult" remote
  - 1     specified        "defult" remote
  - 2     specified        specified
