Wrong name of base images (type=distribution) retrieved by datasource

[bhean]

Overview of the Issue

I can't retrieve the latest version of a base image using the digitalocean-image datasource because the name field of those images only have the version, not the name.

Reproduction Steps

The following code is getting the error Error: Datasource.Execute failed: No matching image found:

data "digitalocean-image" "main" {
  name_regex = "debian.*"
  type   = "distribution"
  region = var.region
  latest = true
}

It looks like the field name only contains the version and the arch of the image on those of type base (or distribution, according to this datasource).

This is a response to get the images from the DigitalOcean API:

curl -H "Content-Type: application/json" -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" "https://api.digitalocean.com/v2/images?page=1&per_page=1000" | jq

Result of that command (I removed redundant parts to keep it small):

{
  "images": [
    {
      "id": 112379295,
      "name": "Convoy 0.6.0 on Ubuntu 20.04",
      "distribution": "Ubuntu",
      "slug": "convoy",
      "public": false,
      "type": "application",
...
    },
    {
      "id": 112929454,
      "name": "20.04 (LTS) x64",
      "distribution": "Ubuntu",
      "slug": "ubuntu-20-04-x64",
      "public": true,
      "type": "base",
...
    },
    {
      "id": 113137715,
      "name": "Nakama 3.12.0 on Ubuntu 18.04",
      "distribution": "Ubuntu",
      "slug": "nakama-18-04",
      "public": false,
      "type": "application",
...
    },
    {
      "id": 114133748,
      "name": "Odoo 14 on Ubuntu 20.04",
      "distribution": "Ubuntu",
      "slug": "bigcloud-odoo",
      "public": false,
      "type": "application",
...
    },
    {
      "id": 114445163,
      "name": "RStudio 2021.09.2+382 on Ubuntu 20.04",
      "distribution": "Ubuntu",
      "slug": "rstudio-20-04",
      "public": false,
      "type": "application",
...
    },
    {
      "id": 168639152,
      "name": "11 x64",
      "distribution": "Debian",
      "slug": "debian-11-x64",
      "public": true,
      "type": "base",
   }
...

Note that images with type=base only has a version on the name field, so I can't get (for example) the latest Debian image because the datasource only get images based on the name field (and there is no "debian" or any other name there)
