We seem to have ended up with a duplicate assert code 40088 between these two places:
https://github.com/mongodb/mongo/blob/d5d4b4945fabfb772b758b95fbfa698c4448484e/src/mongo/util/generate_icu_init_cpp.py#L110
https://github.com/mongodb/mongo/blob/d5d4b4945fabfb772b758b95fbfa698c4448484e/src/mongo/db/repl/replication_coordinator_impl.cpp#L767

I believe this is because buildscripts/errorcodes.py isn't looking in .py files, but it probably can be easily adapted to do so.

This issue is important because we actually have a problem report from the field with this exact error code.
