ci: display tool version more selectively
The goal here is to avoid showing tool version in all case as this create issue
for non linux/docker runner that might not have some of them installed. This is
currently relevant for the coming mac runner that does not have clang-format
installed and does not needs its.
This might also be useful in the future to use narrower docker image more specialized
for each jobs.
