Revert "Disable recipe roller until mac XCode update failure is fixed"

This reverts commit bd7cef84462eb3f5d4338f424332364b109bfc5c.

Reason for revert: We have tested removing the cache, and also manually rolling to the new version, so we can fix the breakage if it reoccurs.

Original change's description:
