Refactor stackHorizontal for dynamic column counts

- Updated the stackHorizontal method to stack card configurations into
  horizontal stacks based on their type.
- Changed the parameter from a single columnCount to an object mapping
  card types to their respective column counts, allowing for greater
  flexibility.

-   * Splits an array of card configurations into horizontal stack card configurations.
+   * Stacks an array of Lovelace card configurations into horizontal stacks based on their type.
    *
-   * Each horizontal stack contains a specified number of cards.
+   * This method processes sequences of cards with the same type and applies a specified column count
+   * for each type of card.
+   * It returns a new array of stacked card configurations, preserving the original order of the cards.
    *
-   * @param {LovelaceCardConfig[]} cardConfigurations - Array of card configurations to be stacked.
-   * @param {number} columnCount - Maximal number of cards per horizontal stack.
+   * @param cardConfigurations - An array of Lovelace card configurations to be stacked.
+   * @param [columnCounts] - An object mapping card types to their respective column counts.
+   *                         If a type is not found in the mapping, it defaults to 2.
+   * @returns An array of stacked card configurations, where each configuration is a horizontal stack
+   *          containing a specified number of cards.
+   *
+   * @example
+   * ```typescript
+   * stackedCards = stackHorizontal(card, {area: 1, "custom:card": 2});
+   * ```
