When tags field should be updatable without recreating the folder.

Actual Behavior

  # google_folder.department1 must be replaced
-/+ resource "google_folder" "department1" {
      ~ create_time         = "2024-09-24T15:52:01.074Z" -> (known after apply)
      ~ folder_id           = "22874620744" -> (known after apply)
      ~ id                  = "folders/22874620744" -> (known after apply)
      ~ lifecycle_state     = "ACTIVE" -> (known after apply)
      ~ name                = "folders/22874620744" -> (known after apply)
      - tags                = { # forces replacement
          - "tagKeys/281482284615220" = "tagValues/281481045753841"
        } -> null
        # (3 unchanged attributes hidden)

Hi @imrannayer!

This is considered a normal behavior since according to terraform registry this field is immutable and causes resource replacement when mutated.

@ggtisc this will make the feature unusable. I am using google_tags_tag_binding to attach bindings instead of directly passing tags values in google_folder to avoid this problem.

I'm forwarding this to check if it is possible an enhancement in future releases
