[Enhancement]: Support event subscriptions in vault_policy_document data source

[gg718]

Description

For Enterprise users, it is possible to configure events/subscriptions via policies.

Would it be possible to add support for this?

vault_policy_document data source

Potential Terraform Configuration

data "vault_policy_document" "example" {
  rule {
    path                  = "secret/*"
    capabilities          = ["list", "subscribe"]
    subscribe_event_types = ["*"]

@fairclothjm #2293 does not address this request, e.g. subscribe_event_types is not supported by vault_policy_document.
