Support inline keyboard callback buttons alongside existing URL/Login buttons.

[o-ray-o]

In https://docs.elizaos.ai/plugin-registry/platform/telegram/complete-documentation , there is this portion that covers inline keyboards and how to utilise plugin-telegram to create them.

const keyboard = {
  inline_keyboard: [[
    { text: "Option 1", callback_data: "opt_1" },
    { text: "Option 2", callback_data: "opt_2" }
  ], [
    { text: "Cancel", callback_data: "cancel" }
  ]]
};

However, going through https://github.com/elizaos-plugins/plugin-telegram/blob/1.x/src/utils.ts
reveals

/**
 * Converts Eliza buttons into Telegram buttons
 * @param {Button[]} buttons - The buttons from Eliza content
 * @returns {InlineKeyboardButton[]} Array of Telegram buttons
 */
export function convertToTelegramButtons(buttons?: Button[] | null): InlineKeyboardButton[] {
  if (!buttons) return [];
  return buttons.map((button: Button) => {
    switch (button.kind) {
      case 'login':
        return Markup.button.login(button.text, button.url);
      case 'url':
        return Markup.button.url(button.text, button.url);
    }
  });
}

which means that the functionality in the documentation was not actually implemented
