This commit moves all already released assets into the released directory and drops the charts associated with them.
The primary purpose of moving assets to this directory is to avoid having the scripts validate rc versions for charts that have already been released. Since our source branch already validates against the main branch, it will already ensure that we do not release a new version of the chart without updating the packageVersion.
The helm index was also regenerated so that the download URLs emitted on trying to download an old asset from the staging branch will still work.
```bash
helm repo index --merge ./released/assets/index.yaml --url released/assets released/assets
```
