Improve arrays during inspect

[sihu]

From output it's not clear that this is an array because of line breaks:

(byebug) bundle_price.bundle
> bundle
{:product=>{:href=>"*****"}, :options=>[], :bundle=>[], :base_price_in_cents=>19500, :total_price_in_cents=>19500, :details=>{:samba_sales_unit_code=>"LCLG"}}
{:product=>{:href=>"*****"}, :options=>[{:categories=>[], :type=>"CATEGORY_REACH_EXTENSION", :price_in_cents=>0}, {:directory_cities=>[{:href=>"*****"}], :type=>"DIRECTORY_CITY_REACH_EXTENSION", :price_in_cents=>0}, {:name=>"PRESENCE_MANAGEMENT", :type=>"SIMPLE_PRODUCT_OPTION", :price_in_cents=>89000}], :bundle=>[], :base_price_in_cents=>89500, :total_price_in_cents=>178500, :details=>{:samba_sales_unit_code=>"LBBHLG"}}
(byebug) bundle_price.bundle.first
