How to: Bump Helm chart versions
To bump the patch version of your Helm chart, run `arkade chart bump -f ./chart/values.yaml`. This updates the patch component of the version specified in Chart.yaml.

```bash
arkade chart bump -f ./charts/flagger/values.yaml
charts/flagger/Chart.yaml 1.36.0 => 1.37.0
```

By default, the new version is written to stdout. To bump the version in the file, run the above command with the `--write` flag.
To bump the version in the chart's Chart.yaml only if the chart has any changes, specify the `--check-for-updates` flag:

```bash
arkade chart bump -f ./charts/flagger/values.yaml --check-for-updates
no changes detected in charts/flagger/values.yaml; skipping version bump
```

The directory that contains the Helm chart should be a Git repository. If the flag is specified, the command runs `git diff --exit-code
` to figure out if the file has any changes.
