How to set "Runtime" Ruby 3.2 instead of default Python 3.10

[ajitAccenture]

Describe the bug
I am creating cloud function which is used to deploy ruby code from repo , but not able to find which varaible or enviroment varaible need to set Runtime" Ruby 3.2 instead of default Python 3.10.

Environment

module "cf_pubsub_trigger" {
  source      = "./fabric/modules/cloud-function-v2"
  project_id      = "modules-4071"
  name            = "moduletest-cf-pubsub-trigger"
  service_account = "[email protected]"
  bucket_name     = "bkt-cftest-00"
  bundle_config = {
    source_dir  =  "test-pubsub/src/"
    output_path = "test-archive.zip"
  }
  environment_variables = {GOOGLE_FUNCTION_SOURCE = "app.rb",  GOOGLE_ENTRY_POINT = "ruby app.rb", GOOGLE_RUNTIME_VERSION=3.2 }
  trigger_config = {
    event_type   = "google.cloud.pubsub.topic.v1.messagePublished"
    pubsub_topic = module.pubsub-topic.id
  }
  depends_on = [module.pubsub-topic]
  vpc_connector = {
    create          = false
    name            = "projectsdev-4743af0/locations/europe-west3/connectors/vpc-conn-risk-1"
    egress_settings = "ALL_TRAFFIC"
  }
}

output from `git rev-parse --short HEAD`

To Reproduce
Apply Above code

Expected behavior
It should show Runtime" Ruby 3.2 instead of default Python 3.10, so that cloud function deployed successfully with ruby code

Result
Geting below error
Error: Error waiting to create function: Error waiting for Creating function: Error code 3, message: Could not create or update Cloud Run service test-cf-pubsub-trigger, Container Healthcheck failed. Revision 'moduletest-cf-pubsub-trigger-00001-sub' is not ready and cannot serve traffic. The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable. Logs for this revision might contain more information.
