[BUG] Hetzner Cloud state ignores config values

[HerHde]

Description
Using the Hetzner Cloud module in a state ignores the configured values in /etc/salt/cloud.providers.d/ or /etc/salt/cloud.profiles.d/ and only takes state attributes, as mentioned in #61392.

Setup

I installed salt-minion, salt-master and salt-cloud on a Hetzner Cloud Debian 11 machine, generated said ssh key, added it to the hetzner cloud, generated an API key there and added some configs to my machine:

/etc/salt/cloud.providers.d/hetzner.conf:

hetzner:
  key: <my API key>
  private_key: /root/.ssh/id_ed25519
  ssh_keys:
    - id_ed25519
  location: fsn1
  driver: hetzner
  minion:
    <additional minion conf>

/etc/salt/cloud.profiles.d/hetzner.conf:

cx21_hetzner:
  provider: hetzner
  image: debian-11
  size: cx21
  location: nbg1

My cloud-hetzner.sls:

my-instance-name:
  cloud.present:
    - name: <machine name>
    - cloud_provider: hetzner
    - image: debian-11
    - size: cx21

Steps to Reproduce the behavior

1. Apply the mentioned state, the new VM will ignore location and ssh_keys, if not configured in the state.

Expected behavior

Search and return a setting in a known order:

1. In the virtual machine's configuration
2. In the virtual machine's profile configuration
3. In the virtual machine's provider configuration
4. In the salt cloud configuration if global searching is enabled
5. Return the provided default

Additional context

Using config.get_cloud_config_value() instead of vm_.get() provides the expected behaviour. PR incoming.
