TLS handshake timeout when listing bazel versions from GCS

I've been regularly seeing an error that looks like some issue with the CI scripts talking to GCS.

The error is a bit confusing because it looks like some problem uploading the test logs ("can't find file"), but also looks like some problem "listing bazel versions in GCS" (whatever that means).

Pressing retry on build kite almost always fixes this, so it's some sort of flake.
