all filter api docs should hide the first array argument from all usage examples

[IgorMinar]

good example is: https://docs.angularjs.org/api/ng/filter/orderBy

which shows usage as:

{{ orderBy_expression | orderBy : array : expression : reverse}}

it should be:

{{ orderBy_expression | orderBy : expression : reverse}}

@petebacondarwin can you please look into this one?
