While using the `--debug` option, the output of helm seems to be printed triple times:
```

```
- The first with the prefixes `helm:MRAjW>` comes from <https://github.com/roboll/helmfile/blob/563fce4adf7abf759ec31b3971d1195704621052/pkg/helmexec/runner.go#L59-L65>
- The second one with the format `exec: helm ... --debug: ...` comes from <https://github.com/roboll/helmfile/blob/563fce4adf7abf759ec31b3971d1195704621052/pkg/helmexec/exec.go#L369>
- And the last are the logs of non-debug mode.
It sometimes makes the log a bit confusing, while I first time read the log, I thought helmfile executed helm command multiple times 😅.
Since we already piped helm outputs to stdout (the first), we remove the second logs.
* Parse and process helm version using github.com/Masterminds/semver/v3.
* Add --force-update only when Helm version >= 3.3.2, < 3.3.4.
See: https://github.com/helm/helm/pull/8777.
* Add test cases.
