Incorrect references to `terraform_remote_state`

Currently completion for calls to the terraform_remote_state source are pretty wonky.

Here are a few examples:

This is good so far

Not good, no option for outputs

Syntax highlighting does (kind of) work properly

Thank you for the report @rtizzy! I was able to reproduce it with the following config:

data "terraform_remote_state" "name" {
  backend = "remote"
  config = {
    hostname = "value"
  }
}

locals {
  test = data.terraform_remote_state. # completion HERE
}

This is almost certainly a bug. We'll need to treat terraform_remote_state as an edge case, where we don't interpret the body of the data source as data, like with other resources and data sources.
