fix: 🐛 Tags and Topics page generating (#11)

## Status
**READY**

## Description
- Fix Tags and Topics pages generating.

The reason is `topic` and `tag` keys are plural in other places but it
is singular in JSON data `lookups`.

## Follow-up
- `lookups` dict keys should also be plural in JSON data.
