[ruby/irb] Fix compatibility with rails before 5.2
Rails before 5.2 added Array#append as an alias to Array#<< ,
so that it expects only one argument.
However ruby-2.5 added Array#append as an alias to Array#push
which takes any number of arguments.
If irb completion is used in rails c (for example "IO.")
it fails with:
irb/completion.rb:206:in `<<': wrong number of arguments (given 3, expected 1) (ArgumentError)
Using Array#push instead of Array#append fixes compatibility.
