Design: Customize labels for specified users (just FYI)

[typed-sigterm]

Issue: #1328

Where to configurate

Possible ways:

1. use data attributes on <script>

   <script src="https://giscus.app/client.js"
     ...
     data-user-labels="<configuration after JSON serialization>"
   ></script>

2. add to giscus.json
3. only by parent-to-giscus message events

Configuration

Possible structures:

1. id-label mapping

   {
     "145281501": "Inactive Collaborator"
   }

2. username-label mapping

   {
     "Zihan-Hu": "Inactive Collaborator"
   }

3. like 1 and 2, but in an array

   [
     // id and/or username
     {
       id: 145281501,
       // username: "Zihan-Hu"
       label: "Inactive Collaborator"
     }
   ]

4. label-id/usernane mapping

   {
     // id and/or username
     "Inactive Collaborator": [145281501, "Zihan-Hu"]
   }
