Feature Request: Support custom container for dataflow

[Jmainguy]

TL;DR

https://cloud.google.com/dataflow/docs/guides/using-custom-containers allows using a custom container, I cannot figure out how to do that using this module. It would be great if this module had an input of a custom container to use.

Detailed design

Wiz found some security issues in our VM we provisioned using this terraform module, it complained that the image "dataflow.gcr.io/v1beta3/windmill@sha256:a8128928e42730f5d5cba4ddefef8bf49969575c4f47d890767f34867eebef4c" contained this CVE https://security-tracker.debian.org/tracker/CVE-2023-31484

It would be great if we could patch this image, and then using terraform have our dataflow use the new patched image via an input like "custom-container-image", where the default if not set would use the default image google recommends.
