hcloud-k3s doesnt work with v3.3.0

When i try to run the the terraform plan i get the following error:

╷
│ Warning: Redundant empty provider block
│
│   on .terraform/modules/k3s_example_hcloud-k3s/examples/hcloud-k3s/main.tf line 1:
│    1: provider "hcloud" {}
│
│ Earlier versions of Terraform used empty provider blocks ("proxy provider configurations") for child modules to declare their need to be passed a provider configuration by their
│ callers. That approach was ambiguous and is now deprecated.
│
│ If you control this module, you can migrate to the new declaration syntax by removing all of the empty provider "hcloud" blocks and then adding or updating an entry like the
│ following to the required_providers block of module.k3s_example_hcloud-k3s:
│     hcloud = {
│       source = "hetznercloud/hcloud"
│     }
╵
╷
│ Error: Iteration over null value

│   on .terraform/modules/k3s_example_hcloud-k3s/server_nodes.tf line 12, in locals:
│   12:   install_env_vars = join(" ", [for k, v in var.k3s_install_env_vars : "${k}=${v}"])
│     ├────────────────
│     │ var.k3s_install_env_vars is null
│
│ A null value cannot be used as the collection in a 'for' expression.
╵

The Warning can be fixed when we remove the provider block from the main.tf in hcloud-k3s:

provider "hcloud" {}

And the Error can be fixed when we add this check to the variable in the server_nodes.tf in the main module:

install_env_vars = var.k3s_install_env_vars == null ? "" : join(" ", [for k, v in var.k3s_install_env_vars : "${k}=${v}"])
