create-astro@4.13.0

#14115 270e009 Thanks @ascorbic! - Removes "Open in x" badges from the README of the official Astro templates when a new project is created
#14115 270e009 Thanks @ascorbic! - Adds support for marking sections in template READMEs to be removed when the create astro command is used to create a new project

Theme authors can now use magic comments in template READMEs to mark sections that should not be included when a user runs create-astro with the --template flag to create a new project.

This allows templates to have content that is visible when viewed in the source repo but not when the template is copied for use in a new project. This is useful for content that is appropriate for a theme's own repository, but will not be useful to someone using the theme, such as
an "Open this repository in StackBlitz" badge where the URL is hardcoded .

Use the magic comments and to indicate content to be excluded from your README during the create astro process.
```
[![Open in StackBlitz](https://developer.stackblitz.com/img/open_in_stackblitz.svg)](https://stackblitz.com/github/withastro/astro/tree/latest/examples/basics)
```
Note that these comments only remove content when new projects are created using create astro. When your theme template is forked, your README will be copied in its entirety.
