json_pure is trowing warnings in ruby 2.7

[brodock]

One of the transient dependencies from packagecloud-ruby gem is json_pure, and it is locked to a very old version: 1.8.1. Running pacakge_cloud in ruby 2.7 is throwing warnings due to the kwargs deprecations for future 3.0 compatibility:

./builds/gitlab-org/build/omnibus-gitlab-mirror/gems/ruby/2.7.0/gems/json_pure-1.8.1/lib/json/common.rb:155: warning: Using the last argument as keyword parameters is deprecated

I remember from a discussion in the past that package_cloud gem was still support ruby 1.8 (which I think is why you are locked to this version). Is this still the case? Do you have any intention or are open to a MR that updates some dependencies for newer ruby's compatibility?
