+ * Type guard to check if a group option is a group with overrides
+ * configuration.
+ *
+ * Determines whether a group element is a special configuration object that
+ * contains group settings rather than being a regular group name or newlines
+ * option.
+ *
+ * @example
+ *
+ * ```ts
+ * const groups = [
+ *   'imports',
+ *   { group: 'foo', commentAbove: '// Components' },
+ *   'components',
+ *   { newlinesBetween: 1 },
+ *   'utils',
+ * ]
+ *
+ * isGroupWithOverridesOption(groups[0]) // false (string)
+ * isGroupWithOverridesOption(groups[1]) // true
+ * isGroupWithOverridesOption(groups[3]) // false (newlines option)
+ * ```
+ *
+ * @param groupOption - A single element from the groups configuration array.
+ * @returns True if the element is a group with overrides configuration object.
