Issue with destroying collection

From the readme, this is a valid use case:

instances = [instance1, instance2]
MyModel.with_explicit_persistence_for(instances) do
  instances.destroy_all
end

However, instances is an array, whereas destroy_all is a method on ActiveRecord_Relation, and passing in a relation causes a Sorbet error. I could make this work as follows:

instances = MyModel.where(some_criteria)
MyModel.with_explicit_persistence_for(instances.to_a) do
  instances.destroy_all
end

but I would think with_explicit_persistence_for should allow an ActiveRecord_Relation to be passed in.

I can draft a PR when I have some free time.

Start with the README example and trace the implementation of with_explicit_persistence_for, especially how it handles an ActiveRecord_Relation versus an array. Check the existing behavior around destroy_all and Sorbet errors. Done means the documented relation use case works without requiring to_a and is covered by the project's relevant checks.
