| # Description: | |
| # This workflow automates the process of checking for and updating Helm chart dependencies. | |
| # Specifically, it: | |
| # 1. Checks for new versions of (subchart) dependencies listed in chart.yaml. | |
| # 2. Updates chart.yaml with new versions where applicable. | |
| # 3. If the 'opentelemetry-operator' subchart is updated in chart.yaml, it also updates related | |
| # image tags in values.yaml. | |
