Description
The current signature for Array#zip accepts exactly one array argument, but the actual zip acceptes one or more arrays. Can we write a signature for this?
pp [1, 2, 3].zip(%w(foo bar baz), [:foo, :bar, :baz])
#=> [[1, "foo", :foo], [2, "bar", :bar], [3, "baz", :baz]]

Research direction
The issue names Array#zip but no files or tests. Start by locating the current Array#zip signature and checking how RBS represents arguments of variable length; done means the shown call with two arrays is accepted while the existing one-array behavior remains valid.
