[BUG] npm 9.7.0

## Affected builder image

[eu.gcr.io/gae-runtimes/buildpacks/google-gae-18/nodejs/builder:nodejs_20230529_RC00](http://eu.gcr.io/gae-runtimes/buildpacks/google-gae-18/nodejs/builder:nodejs_20230529_RC00)

## Expected Behavior

My project gets deployed to AppEngine (Node.js 16)

## Actual Behavior

The build aborts with the following:

## Steps to Reproduce the Problem

Update / install any dependency so as to cause a CACHE_MISS, then try to upload. If there is a CACHE_HIT then the error doesn't get triggered.

## Additional Info

npm 9.7.0 was deprecated a matter of hours after its initial release: https://github.com/npm/cli/releases/tag/v9.7.0

I think you need to rebuild the Cloud Build image with npm 9.6.x to resolve this issue.
