Also update chart_version.sh script which
counts the number of commits since the BASE_VERSION
if BASE_VERSION tag is found. If the tag
doesn't exist it counts the number of commits since the
beginning. So when we use for example 2025.1.0 as
the BASE_VERSION but the tag 2025.1.0 is not yet created
the version of the e.g. nova chart will be calculated as
like 2025.1.563+<sha> and then when we create tag the nova version
will be 2025.1.0+<sha> which is undesired.
Lets use BASE_VERSION-<sha> if the tag is not found.

This change makes it possible to use identical
chart_version.sh script in both git repos
openstack-helm and openstack-helm-infra.
This is to prepare for the upcoming merger with
openstack-helm-infra and to reduce the number
of merge conflicts.
