aider: Added a scope with a custom description for the examples section in _config.yml.

# Context:
USER: can i use scope to apply a different description to different parts of the site?
ASSISTANT: Yes, you can use the `scope` feature in Jekyll to apply different descriptions to different parts of the site. You'll need to modify the `_config.yml` file to define the scopes and their respective descriptions.

Here's a step-by-step guide to achieve this:

1. In the `_config.yml` file, add a new `defaults` section.
2. Define the scope by specifying the `path` and `type` attributes.
3. Set the `values` attribute to include the `description` key with the desired description text.

Here's an example of how to add a scope with a custom description for the `examples` directory:

```yaml
_config.yml
<<<<<<< ORIGINAL
theme: jekyll-theme-cayman
=======
theme: jekyll-theme-cayman

defaults:
  - scope:
      path: "examples"
      type: "pages"
    values:
      description: "This is a custom description for the examples section."
>>>>>>> UPDATED
```

This will apply the custom description to all pages within the `examples` directory. You can add more scopes for other directories or specific pages by following the same pattern.
