DigitalOcean Image Remove

This action uses doctl to find and remove old images from Digital Ocean's Container Registry.

1. Gets the repository manifests using doctl registry repository lm and orders them by the UpdatedAt attribute. By default it will ignore the 10 most recent images
2. Then deletes the older images using doctl registry repository delete-manifest

PRs are welcome.
