Constant WIKI_GRID_CREATE 

pub const WIKI_GRID_CREATE: &str = "\
Create an empty grid on a Yandex Wiki page.

```
ytcli wiki create-grid users/ilubenets/runbook --title \"Releases\"
```

The grid starts with no columns: `wiki columns-add` gives it some. The Wiki
makes a grid a resource of the page, and showing it inside the page's text is
done in the Wiki's editor. Prints the new grid's id and revision. The profile
and organisation are announced first, and `--dry-run` sends nothing.";
