# This script sets the chart versions, given a destination helm repository, git commit SHA, and optionally a git tag.
# If the tag is empty, each chart version is set to the current version, suffixed with that sha
# If the tag is non-empty, each chart version is set to that tag
# Because the multitenant chart depends on the standalone chart, the provided repo is set as the dependency url
# Finally, the appVersion of each is set to the tag, if present, else the sha, with no prefix or suffix
