git 22.0 tag is not standard and jenkins fails

[paskino]

Jenkins determines the number of commits from the latest tag with these lines

https://github.com/vais-ral/CCPi-VirtualMachine/blob/40bc2d32a16db85974775a00789333f3b01b433f/scripts/jenkins-build.sh#L50-L51

export CIL_TAG_PREV=$(git describe --tags --abbrev=0 | tr -d '/s/v//g' )
ncommits=$(git rev-list v${CIL_TAG_PREV}..HEAD --count)

In particular the second line assumes that the tag has a v in it as first character. Since the latest tag is 22.0, this fails.
