Can't use password field in another provider

Hi,

i try to use the terraform onepassword provider to fetch token for another provider in this way:

```
terraform {
required_providers {
hcloud = {
source = "hetznercloud/hcloud"
}
onepassword = {
source = "1Password/onepassword"
}
}
}

provider "onepassword" {
url = "http://localhost:8080"
}

data "onepassword_item" "hcloud_token" {
vault = "the-uuid"
title = "Hetzner Cloud Token - Test"
}

provider "hcloud" {
token = data.onepassword_item.hcloud_token.password
}
```

When i use data.onepassword_item.hcloud_token.password i get the error "The argument "token" is required, but no definition was found."

After several try & error iterations i then copied the token in the url field in 1password and used data.onepassword_item.hcloud_token.url and this works. In both fields is exact the same string. Any idea why i cant use the password field here?
