fix: Add project ID to the fleet feature membership for ASM

[legal90]

That resource was added recently in #1702

Bit I get this error when I try to apply it with my config:

# module "gke" { ... }

module "asm" {
  source = "git@github.com:terraform-google-modules/terraform-google-kubernetes-engine.git//modules/asm?ref=3c9a634ceef3fe8fc073de161f17f0064f424c04"

  project_id                = var.project_id
  cluster_name              = module.gke.name
  cluster_location          = module.gke.location
  mesh_management           = "MANAGEMENT_AUTOMATIC"
  multicluster_mode         = "connected"
  enable_cni                = true
  enable_fleet_registration = true
  enable_mesh_feature       = true
}

$ terraform plan

I fix it in this PR just by adding project argument explicitly.
After that fix it works as expected.
