Subject: [PATCH] Make mantle ref bump action more robust

The curl call to download the current version.txt file failed, causing
branch to be "flatcar-" which later lets the git checkout fail. This
was hidden somewhere in the logs of successful steps.
To directly stop execution, use saner settings for curl and bash.
