Vincent Ambo a9dd719e7c chore(tvl-buildkite): Add jq and curl to agent paths
This is required for a simplification of the build pipeline (following
CL) and needs to be in a separate commit as it can not be done
atomically (merging the other commit to deploy it would immediately
break pipelines otherwise).
