add TagWiki table

Sanity check code:

```py
tagwiki = TagWiki.select().order_by(fn.Random()).limit(1).first()
print(f"Title {tagwiki.title}")
print(f"Body {tagwiki.body}")
print(f"Created at {tagwiki.created_at}")
print(f"Updated at {tagwiki.updated_at}")
print(f"Is locked {tagwiki.is_locked}")
print(f"Is deleted {tagwiki.is_deleted}")
print(f"Other names {tagwiki.other_names}")
print(f"Tag id {tagwiki.tag_id}")
print(f"Tag name {Tag.get_by_id(tagwiki.tag_id).name}")
```

The `deleted` wiki is not added, and for multiple wiki pages, the only one with newest date + not deleted state is reflected.
