Not sure how this PR is green as the spec fails when I run it locally 😕

  1) ConfigCat::ConfigCatClient test flag_overrides
     Failure/Error: @_override_data_source = options.flag_overrides.create_data_source(@log)

     NoMethodError:

Hi @irwalker, thanks for pointing this out! I had to manually enable the CI actions for this PR, which is why you didn't see the failures yet. We are started working on the fix.
