Unable to start vault agent (version 1.18.0) in Windows

[esenmarti]

Describe the bug
Creating a vault agent in Windows with the new 1.18.0 version fails with error creating file sink: error during write check: error changing ownership of XXX: chown XXX: not supported by windows

To Reproduce
vault.exe agent -config="config.hcl"

Expected behavior
The vault agent starts (this is what we see in the same env when using 1.17.6)

Environment:

• Vault Server Version (retrieve with vault status): 1.15.4
• Vault CLI Version (retrieve with vault version): Vault v1.18.0 (77f26ba), built 2024-10-08T09:12:52Z
• Server Operating System/Architecture: Windows

Vault server configuration file(s):

exit_after_auth = true
pid_file = "/vault/pidfile"

vault {
  address = "xxx"
  retry {
    num_retries = 5
  }
}

auto_auth {
  method "gcp" {
    exit_on_err = true
    mount_path = "auth/xxx"
    config = {
      role = "xxx"
      type = "xx"

    }
  }

  sink "file" {
    config = {
      path = "/a/path/"
    }
  }
}

Additional context
It might have been introduced in #27123
