[ISSUE] Issue destroying databricks_workspace_conf after setting maxTokenLifetimeDays field

Configuration

resource "databricks_workspace_conf" "this" {
provider = databricks.workspace
custom_config = {
"enableIpAccessLists" : true,
"maxTokenLifetimeDays": 90
}
}

Expected Behavior

It should be possible to destroy the resource databricks_workspace_conf or to remove the "maxTokenLifetimeDays" field after setting it to some value

Actual Behavior

Currently destroying databricks_workspace_conf is not allowed after setting maxTokenLifetimeDays to a value. It throws the error │ Error: cannot delete workspace conf: Some values are not allowed: {"maxTokenLifetimeDays":""}

Steps to Reproduce

create a databricks_workspace_conf resource

2) Remove or comment the field maxTokenLifetimeDays and run apply or try destroying the entire resource. Terraform will return

Error: cannot update workspace conf: Some values are not allowed: {"maxTokenLifetimeDays":""}

3) Try adding the field "maxTokenLifetimeDays": 90 back and terraform will pass

4) Try destroying the resource after adding maxTokenLifetimeDays back, Terraform will fail with the same error even after adding it back

It looks like once the value maxTokenLifetimeDays is set once, the resource gets into a state where it cannot be destroyed in Terraform

Terraform and provider versions

provider registry.terraform.io/databricks/databricks v1.37.1

Is it a regression?
