/// Code Block component
///
/// > A **code block** is a component that contains 2 or more lines of read-only code. The code in a code block can be copied to the clipboard.
///
/// See: <https://www.patternfly.org/components/code-block>
///
/// ## Properties
///
/// Defined by [`CodeBlockProperties`].
///
/// ## Children
///
/// A code block can contain any children, but is expected to contain a [`CodeBlockCode`] component.
///
/// It may also be wrapped with a detached [`crate::prelude::ExpandableSection`] component. The
/// [`crate::prelude::ExpandableSectionToggle`] would then be a child of this component, but stay outside the nested
/// code component.
///
/// ## Example
///
/// A simple example would be:
///
/// ```rust
/// use yew::prelude::*;
/// use patternfly_yew::prelude::*;
///
/// #[function_component(Example)]
/// fn example() -> Html {
///   html!(
///     <CodeBlock>
///       <CodeBlockCode>{r#"some code"#}</CodeBlockCode>
///     </CodeBlock>
///   )
/// }
/// ```
