Ruby 3.5 compatibility

[padde]

Fixes #121

The ostruct gem was historically included in the default gems included with Ruby. Starting with Ruby 3.3.5 though, requiring ostruct without explicitly adding it as dependency generates the following warning:

warning: ostruct 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.

As of Ruby 3.5, the ostruct gem will then no longer be shipped with Ruby so we need to explicitly add it to the dependencies.
