Dynamic content in Wizard

[const8ine]

Wizard is a component called WizardSheetComponent that displays helpful content to new users.

Show content from WP API, use WordpressApiService to fetch content by a special tag or a category.
Instead of displaying only one page implement adding custom tabs with content. Each tab should consist of a title and a "slug" — a unique name that should be passed to getArticleBySlug method of service to fetch article content.

@const8ine should add a Figma template to the task
