datasource akp_kargo_instance value conversion error

[PleaseMeHaveNoRegrets]

After our last terraform run - it seems that the datasource akp_kargo_instance may have a bug from the provider.

Error: Value Conversion Error

  with data.akp_kargo_instance.prod,
  on kargo-clusters.tf line 5, in data "akp_kargo_instance" "prod":
   5: data "akp_kargo_instance" "prod" {

An unexpected error was encountered while verifying an attribute value
matched its expected type to prevent unexpected behavior or panics. This is
always an error in the provider. Please report the following to the provider
developer:

Expected framework type from provider logic:
types.ObjectType["claims":types.MapType[types.ObjectType["values":types.ListType[basetypes.StringType]]]]
/ underlying type:
tftypes.Object["claims":tftypes.Map[tftypes.Object["values":tftypes.List[tftypes.String]]]]
Received framework type from provider logic:
types.ObjectType["claims":types.MapType[types.ObjectType["values":types.SetType[basetypes.StringType]]]]
/ underlying type:
tftypes.Object["claims":tftypes.Map[tftypes.Object["values":tftypes.Set[tftypes.String]]]]

I am able to replicate this on akuity/akp 0.9.10 - though am able to successfully build a plan on akuity/akp 0.9.5, which was the last successful run of this pipeline from a few weeks ago.

the datasource in question is simply and minimally defined

data "akp_kargo_instance" "prod" {
  name = "prod"
}

more details inline with tf plan
