lib/rubocop/changes/checker.rb needs require 'ostruct'

After an automated dependabot update in a project that uses this gem, I began getting the following error:
% bundle exec rubocop-changes -b develop --format github /Users/justin.auvil/.rvm/gems/ruby-3.1.3@erp/gems/rubocop-changes-0.8.1/lib/rubocop/changes/checker.rb:104:in rubocop_json': uninitialized constant Rubocop::Changes::Checker::OpenStruct (NameError)

    @rubocop_json ||= JSON.parse(rubocop, object_class: OpenStruct)

Seems like an issue with OpenStruct needing to be required in the checker class. I've rebuilt the gem locally adding the requirement, and no issues. Attempted to create a PR but couldn't.

Any updates on this issue? Is the gem is still being maintained?

One way around this is via RUBYOPT

env RUBYOPT="-rostruct" bundle exec rubocop-changes
