[REQUIRED] Environment info

firebase-tools: 12.5.2

Platform: macos

[REQUIRED] Test case

Trying to use a shared vpc from a different project with .env and

FUNCTION_VPC="projects/shared/locations/us-central1/connectors/shared"

const vpc = params.defineString('FUNCTION_VPC');
setGlobalOptions({
  vpcConnector: vpc
});

[REQUIRED] Steps to reproduce

Try to deploy with these values and firebase tools mutates the vpcConnector string to an invalid value.

functions: HTTP Error: 400, Could not update Cloud Run service projects/my-project/locations/us-central1/services/function. spec.template.metadata.annotations: Expected a VPC access connector name like projects/*/locations/*/connectors/*, but obtained projects/not-shared-project/locations/us-central1/connectors/{{the full value of the FUNCTION_VPC}}

I assume the issue is around

But my connector has a / in it so it shouldn't get modified. I wonder if it has to do with the Expression<string> type that has a .value() not being invoked or something until later? Or maybe the / is encoded when read from the environment file?

[REQUIRED] Expected behavior

The VPC value I specify is used

[REQUIRED] Actual behavior

The string is mutated and the deployment fails.
