We do a couple of things here:
- Consolidate requirements.yaml into Chart.yaml
- Remove *.tgz files from the Helm directory
Since we already use JSON schema (https://helm.sh/docs/faq/#validating-chart-values-with-jsonschema), we're already using Helm 3. Here,
we follow another guideline of removing requirements.yaml in favor of Chart.yaml (https://helm.sh/docs/faq/#consolidation-of-requirementsyaml-into-chartyaml).
*.tgz files shouldn't be checked in here. When packaging or installing the repository from source, the --dependency-update should be used.
