Request for chartmuseum org repos to join the Helm org

This request is to cover the following 4 separate repositories. If needed, I can open an issue for each.

- A link back to the project:
- [ ] https://github.com/chartmuseum/auth
- [ ] https://github.com/chartmuseum/helm-push
- [ ] https://github.com/chartmuseum/storage
- [ ] https://github.com/chartmuseum/www

- The GitHub user names of those in a governance role for that project:
- [jdolitsky](https://github.com/jdolitsky)

- A short description (1-3 paragraphs) of why it makes sense to add to Helm:
- Helm has the structure in place to ensure that these projects can be properly maintained in the event that I am hit by a bus or quit computers entirely.

- A short explanation of how the project is to be staffed going forward:
- The projects can be staffed by [jdolitsky](https://github.com/jdolitsky), [ChartMuseum maintainers](https://github.com/helm/chartmuseum/blob/main/OWNERS), and other Helm core maintainers
