Add subcommand update-values to update the swh-charts/values-...yaml

This reads the tags from the input (tags expected to be from the swh-apps repository). Then computes the tags that needs to be updated in the targetted /path/to/swh-charts/values-swh-applications.yaml.

Imagine a jenkins job triggering the clone of the repository swh-charts and swh-apps. Then lists in most recent order the tags from swh-apps to pass along that script. It then updates the swh-charts:/values-swh-applications.yaml. And then commit, push and update the MR already opened with the updates.

$ cd swh-apps
$ git tag -l | sort -r | docker run ... build-deps update-values \
  --value-filepath /path/to/swh-charts/values-swh-applications.yaml
