Useless warning dev_url is unset

[ilya-bukinich]

On configuration:

terraform {
  required_providers {
    atlas = {
      source  = "ariga/atlas"
      version = "0.9.1"
    }
  }
}

provider "atlas" {
  cloud {
    token = var.atlas_token
  }
}

locals {
  db_url          = "clickhouse://localhost:9000"
  migrations      = "${path.module}/migrations?format=atlas"
}

data "atlas_migration" "db" {
  url     = local.db_url
  dir     = local.migrations
}

resource "atlas_migration" "db" {
  dir              = local.migrations
  url              = local.db_url
  version          = data.atlas_migration.db.latest
  revisions_schema = "default"
}

terraform plan returns:

data.atlas_migration.db: Read complete after 1s [id=file://./migrations?format=atlas]

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # atlas_migration.db will be created
  + resource "atlas_migration" "db" {
      + dir              = "./migrations?format=atlas"
      + id               = (known after apply)
      + revisions_schema = "default"
      + status           = (known after apply)
      + url              = (sensitive value)
      + version          = "001"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you run "terraform apply" now.

but for in data source atlas_migration an argument named dev_url is not expected here and is not used in any way
