use asset inventory to list bindings

gcloud asset list --organization $ORG_ID --asset-types cloudresourcemanager.googleapis.com/TagBinding

Ouput like the following:

---
ancestors:
- folders/111
- organizations/999
assetType: cloudresourcemanager.googleapis.com/TagBinding
name: //cloudresourcemanager.googleapis.com/tagBindings/%2F%2Fcloudresourcemanager.googleapis.com%2Ffolders%2F111/tagValues/222
updateTime: '2024-05-16T01:15:55.359Z'
