Summary

This PR updates the version of the Google builder in the KnownBuilders addressing #2199

In this PR, I have removed gcr.io/buildpacks/builder:v1 from both Trusted and Suggested. If there are criteria for being Trusted or Suggested that require keeping v1, please let me know. I will be happy to make the necessary adjustments.

Resolves #2199

Do we want to keep older builders as trusted but not suggested as we do with Heroku?

@natalieparellano , @edmorley

I think the answer is no, but just wanted to double check, otherwise this one looks good to me

[edmorley]

Do we want to keep older builders as trusted but not suggested as we do with Heroku?

For the Heroku builders, we've used the following methodology:

• remove any builders that are EOL (eg those based on Ubuntu 18.04)
• have all other active Heroku builders be trusted
• have only the most recent Heroku builder (which is currently the one based on Ubuntu 24.04) be suggested

Given that the gcr.io/buildpacks/builder:v1 builder is based on Ubuntu 18.04 and so EOL, I think it makes sense to remove it entirely from trusted builders.
