[ISSUE] Issue with databricks_grant resource on external_location introduced on 1.48.0

[krknopp]

Configuration

We're trying to apply grants to an external location

resource "databricks_grants" "main" {
  external_location = "external1"
  id                = (known after apply)

  grant {
      principal  = "GROUP-NAME"
      privileges = [
          "ALL_PRIVILEGES",
        ]
    }
}

Expected Behavior

Grants should be applied

Actual Behavior

Grants aren't applied with it saying it can't find the group by name. It doesn't matter if the group name is specified as lower or upper case, the error always shows lower case. We were wondering if it had anything to do with the case sensitivity being removed in 1.48.0.

Steps to Reproduce

1. terraform apply the above code with provider version 1.48.0.

Is it a regression?

yes, 1.47.0 and 1.46.0 both work properly.

We are also experiencing the exact same issue with 1.48.0, though ours are with catalog/schema grants (almost the same code) rather than external locations, and have confirmed that reverting to 1.47.0 works for us.
