Gem ostruct deprecated from the Ruby standard library

[justinlara]

Hello, the gem ostruct is deprecated from Ruby's standard library and needs to be included explicitly as it will no longer be available in Ruby 3.5. When using HairTrigger, the following warning displays:

warning: <path>/ostruct.rb was loaded from the standard library, but will no longer be part of the default gems starting from Ruby 3.5.0.
You can add ostruct to your Gemfile or gemspec to silence this warning.
Also please contact the author of hairtrigger-1.2.0 to request adding ostruct into its gemspec.

Rails 7.1.3.4
