dev/ci: try to de-emphasize log upload

Created by: bobheadxi

This is often a source of confusion - the log upload might look like the cause of a build failure, but it only ever runs if the build has already fails. This tries to de-emphasize its log output to point towards the real issue.

(Log upload sometimes fails for some reason for another, often log lines that are too long. It's mostly a convenience tool for maintaining observability, and some logs failing to upload is not critical)
