[v3] Add tags

[ErikSchierboom]

This issue is part of the migration to v3. You can read full details about the various changes here.

In Exercism v3, tracks can be annotated with tags. This allows searching for tracks with a certain tag combination, making it easy for students to find an interesting track to join.

Tags are specified in the top-level "tags" field in the track's config.json file and are defined as an array of strings, as specified in the spec.

Goal

The "tags" field in the config.json file should be updated to contain the tags that are relevant to this track. The list of tags that can be used is listed in the spec.

Example

{
  "tags": [
    "runtime/jvm",
    "platform/windows",
    "platform/linux",
    "paradigm/declarative",
    "paradigm/functional",
    "paradigm/object_oriented"
  ]
}

Tracking

I think I can take this. It seems the other merge request has to do with the CI pipelines

Edit: Neeever mind, it does have the tags
