Uprev ChromeScreenAI CIPD to 127.15

This CL updates the CIPD for downloading the library that is used for
ChromeScreenAI browser tests.

If browser tests fail, revert the rollout for the new binary in the
component updater as well. You will need to rollout a newer (or older)
release to update the clients that are affected by the faulty rollout.
