Styling is missing Disabled options

[kobitate]

Dropdown is not showing proper styling for disabled options (Bulloch Animal Shelter in the example below)

{
   "results":[
      {
         "id":"1",
         "text":"Community",
         "disabled":false
      },
      {
         "id":"2",
         "text":"Bulloch Animal Shelter",
         "disabled":true
      },
      {
         "id":"3",
         "text":"Metter Animal Shelter",
         "disabled":false
      },
      {
         "id":"4",
         "text":"Evans County Animal Shelter",
         "disabled":false
      }
   ],
   "pagination":{
      "more":false
   }
}

Select2 default theme:

With this repo theme. item is disabled but not styled as such:

You can correct this by adding this to your site's CSS:

.select2-container--bootstrap4 .select2-results__option[aria-disabled=true] {
    color: #999;
}

I'm open to submitting a PR to fix this, but it seems like the repo is stale (no PRs have been merged since 2019)

I've fixed this into #67
