RFR: 8345874: Run make doctor automatically on failed CI builds

Mon Apr 7 10:29:04 UTC 2025

If there is something wrong with the build, the user can run "make doctor". That is hard to do in a CI setting. Instead, if the build environment is detected to be a CI, we should run the doctor automatically in case of a failed build.
