Problem loading openapi.yml after ruby update to 3.2.7

After we updated Ruby from 3.1.4 to 3.2.7 in our project, we noticed that openapi is failing while generating documentation from tests because there is an error of:

Psych::DisallowedClass:
   Tried to load unspecified class: Date

Relatable stack overflow error https://stackoverflow.com/questions/76825550/tried-to-load-unspecified-class-date-psychdisallowedclass-while-updating-th

We fixed it by monkey patching:

RSpec::OpenAPI::SchemaFile.class_eval do
  def read
    return {} unless File.exist?(@path)

    require 'date'

    RSpec::OpenAPI::KeyTransformer.symbolize(YAML.safe_load(File.read(@path), permitted_classes: [Date])) # this can also parse JSON
  end
end

But I also see that there are tests for ruby 3.3 in https://github.com/exoego/rspec-openapi/blob/master/.github/workflows/test.yml#L26 which is confusing because it would seem that they should not be passing. I can submit a PR with change like in the monkey patch but am I the only one that noticed this error while upgrading Ruby?
