IPI installation using the service account attached to a GCP VM always fail with error "unable to parse credentials"

4.14.0-0.nightly-2023-09-15-233408

Always

1. "create install-config"
2. edit install-config.yaml to insert "credentialsMode: Manual"
3. "create manifests"
4. manually create the required credentials and copy the manifests to installation-dir/manifests directory
5. launch the bastion host along with binding to the pre-configured service account ipi-on-bastion-sa@openshift-qe.iam.gserviceaccount.com and scopes being "cloud-platform"
6. copy the installation-dir and openshift-install to the bastion host
7. try "create cluster" on the bastion host 

The installation failed on "Creating infrastructure resources"

The installation should succeed.
