[rgbkrk]

Summary

Updates ark from 0.1.232 to 0.1.238 to include fixes for history_request and comm_info_request support, improving ark's conformance score from 92% to 100%.

Changes

• Updated ark binary download URL in conformance workflow from 0.1.232 to 0.1.238

Test Plan

The conformance CI workflow will run and verify that ark now passes all required tests, including the previously failing history_request and comm_info_request tests.
