The drud/ddev-gitpod-base docker image gets stale if nobody remembers to update it.

Describe the solution you'd like

• Push on every ddev master push (or daily on nightly build)
• Automatically update ddev's .gitpod.yml to use the updated image (optional)
• Automatically update ddev-gitpod-launcher's .gitpod.yml to use the updated image

I don't think this strategy actually works; it seems you have to push a new tag. Will keep pushing new tags.
