Check current sylvactl version before downloading it
What does this MR do and why?
SYLVA_VERSION variable is now embedded in CI image. So the ensure_sylvactl
function now re-downloads systematically the binary.
This MR just check the current version to avoid downloading if the expected binary is already present (from toolbox).
