Add changed_charts and chart_version outputs (#130)
* Add `changed_charts` and `chart_version` outputs This should let downstream steps make conditional decisions based on what we found. Also: fix a confusing double-negative test in main(). Signed-off-by: Nathan J. Mehl <n@oden.io> --------- Signed-off-by: Nathan J. Mehl <n@oden.io>

- `skip_packaging`: This option, when populated, will skip the packaging step. This allows you to do more advanced packaging of your charts (for example, with the `helm package` command) before this action runs. This action will only handle the indexing and publishing steps.
|
||||
- `mark_as_latest`: When you set this to `false`, it will mark the created GitHub release not as 'latest'.
|
||||
|
||||
### Outputs
|
||||
|
||||
- `changed_charts`: A comma-separated list of charts that were released on this run. Will be an empty string if no updates were detected, will be unset if `--skip_packaging` is used: in the latter case your custom packaging step is responsible for setting its own outputs if you need them.
|
||||
- `chart_version`: The version of the most recently generated charts; will be set even if no charts have been updated since the last run.
|
||||
|
||||
### Environment variables
|
||||
|
||||
- `CR_TOKEN` (required): The GitHub token of this repository (`${{ secrets.GITHUB_TOKEN }}`)
