Schema privileges not applied during deploy

[pocelka]

Describe the issue

I'm testing deployment of various resources via CLI and it seems like even though grants should be supported for schema resource, they are never applied.

Configuration

resources:
  schemas:
    bronze:
      catalog_name: poc
      name: bronze
      comment: "Raw, unmodified data landed exactly as received from source systems. No transformations, no corrections. The immutable audit trail."
      lifecycle:
        prevent_destroy: false
      grants:
        - principal: whatever
          privileges:
            - ALL_PRIVILEGES

Steps to reproduce the behavior

1. Run databricks bundle deploy ...

Expected Behavior

Grants should be applied after deployment.

Actual Behavior

Grants are not applied. Principal is not validated - I can put as principal any value and it will not do anything.

OS and CLI version

OS: Fedora 44
CLI: v1.5.0 (direct deployment mode)
Target: Databricks Free
