Migrate to new google client stuff

[mattgodbolt]

One or more of your web applications uses the legacy Google Sign-In JavaScript library. Please migrate your project(s) to the new Google Identity Services SDK before March 31, 2023.
Hello Google Developer,

You are receiving this message as a reminder that one or more of your web applications uses the legacy Google Sign-In web solution. Our announced plan stated that support for the Google Sign-In JavaScript platform library will be deprecated after March 31, 2023. Additionally, we would like to apologize for any impact this change may have on your organization, and we will do our best to support you through this transition.

Please know that the legacy library will still be available for download by existing clients. A sunset date, after which the legacy library will no longer be available for use, will be communicated in the future.

What do I need to know?
To help you find out which of your web apps or environments are affected, we’re sharing a list of your client ID(s) that use the legacy Google Sign-In web solution. This list should help you evaluate user impact and prioritize the migration work more efficiently. If you have Google Cloud Platform (GCP) console login issues, Google Cloud Support can help you. Please file a ticket with the Support Hub.
