Google Cloud does not allow outgoing port 25 except to their authorized email relay service providers, whom you pay based on the volume of email you are sending.

You’ll need to contract with one of those providers to send email out from your Zimbra server if you want to continue to host on Google Cloud.

I have nerver used google vm but if you have only one domain on zimbra server, you can try Mailgun. The free plan has 10000 email per month. Mailgun is a relay service.
