[infra] Put GCP artifact registry cleanup policies into terraform

[jigold]

What happened?

See #13489 for context. We want to use terraform to keep track of artifact registry cleanup policies once it is available in Terraform.

Relevant links:
hashicorp/terraform-provider-google-beta@bc4aa51
hashicorp/terraform-provider-google#13824

It's not in 4.79.0 (see what was added since then). Releases appear to happen ~once a week, so we should be able to import into terraform in September.

Version

0.2.120

This is now available in 4.80.0 through 5.2.0. Work for this issue is:

1. Upgrade to latest 4.x.x
2. Encode cleanup policies in terraform.
