/// Converts a `String` to kebab case.
///
/// Kebab case is a string converted to lowercase with any spaces, underscores,

/// # Arguments

/// * `s` - The input string to be converted to kebab case.
///
/// # Returns
///
/// Returns a new string converted to kebab case.
///
/// # Examples
///
/// ```rust
/// use lorust::kebab_case;
///
/// let kebab_cased = kebab_case("Foo Bar".to_string());
/// assert_eq!(kebab_cased, "foo-bar");
/// let kebab_cased = kebab_case("fooBar".to_string());
/// assert_eq!(kebab_cased, "foo-bar");
/// let kebab_cased = kebab_case("__FOO_BAR__".to_string());
/// assert_eq!(kebab_cased, "foo-bar");
/// ```
