Update Google's suggested builder
Description
Currently the Pack CLI's suggested builders list contains an outdated Google builder image, gcr.io/buildpacks/builder:v1
, which is based on the EOL Ubuntu 18.04 LTS:
https://github.com/buildpacks/pack/blob/ce8db3c5d11b8e040fd565632668a697e53e4f87/internal/builder/known_builder.go#L12-L18
Proposed solution
- Add one of the newer Google builder images documented here: https://cloud.google.com/docs/buildpacks/builders
- Then either remove
gcr.io/buildpacks/builder:v1
from the suggested/trusted builders list entirely, or demote it to only being a "trusted" builder and not also a "suggested" builder (now that the concepts are separate, after https://github.com/buildpacks/pack/pull/2043)
Describe alternatives you've considered
Continue to suggest a builder image that uses an EOL and insecure Ubuntu version.
