ci: enable info logging in publish workflow as a debugging aid

To find out why publishing sporadically fails, this commit enabled
Gradle info logging in the publish workflow. Gradle would log HTTP
request retries on this level and maybe they are the source of our
sporadic redeployment issues. Info level should be safe to stay enabled
as it does not leak credentials or something else.
