[chore] Linter warns about title level 1 even if you change it

[crazyserver]

What do we need to do?

On metadata you can specify a title that will be displayed in 3 places:

• Sidebar / menus
• HTML head title tag.
• Level 1 title on page.

If you want the title from sidebar and level 1 differ, you have to write a new level 1 title using a single hash, but then the linter warns you.

Don't use the Markdown to change the heading, use frontmatter:

---
title: Example title
sidebar_label: Alternate label in the sidebar
