Invalid Bigtable instance_id length error in GCP terraform module

[vijay-wandb]

The Bigtable instance created using @danielpanzella Terraform GCP branch at SSI (link) threw an error due to an invalid instance_id length

│
│   with module.wandb.module.bigtable[0].google_bigtable_instance.default,
│   on terraform-google-wandb/modules/bigtable/main.tf line 5, in resource "google_bigtable_instance" "default":
│    5: resource "google_bigtable_instance" "default" {

Just a FYI: The customer's workaround involves padding the namespace to meet the required length, but this may not work for us.
