Improve usage example for model generator decimal field

[ka8725]

We should wrap parameters to quotes when pass parameters with curly braces to decimal generator because the shell (tested in bash and zsh) transforms them to several params. Example:

$ echo p{1,2}
p1 p2

So actual example (rails generate model product price:decimal{10,2}) generates migration like this:

class CreateProducts < ActiveRecord::Migration
  def change
    create_table :products do |t|
      t.decimal10 :price
      t.decimal2 :price

      t.timestamps
    end
  end
end

Fixed version of the command (rails generate model product 'price:decimal{10,2}') generates correct migration:

class CreateProducts < ActiveRecord::Migration
  def change
    create_table :products do |t|
      t.decimal :price, precision: 10, scale: 2

      t.timestamps
    end
  end
end
