Update 01-pages-and-layouts.mdx (#55795)
```
Pages and Layouts
The Pages Router has a file-system based router built on the [concept of pages](https://nextjs.org/docs/pages/building-your-application/routing/pages-and-layouts).
```
Change requested:
Here `concept of pages` hyperlinks routes to the current page. This bit confusing for someone trying to learn next.js. removing the hyperlink to the text would make clear.
