KeyboardButtonRequestChat with chat_is_channel == false doesn't add the bot to the chat.

Steps to reproduce

An example of bot markup where it's reproducible:

const _kBotAdminRights = ChatAdministratorRights(
  isAnonymous: true,
  canManageChat: true,
  canDeleteMessages: false,
  canManageVideoChats: false,
  canRestrictMembers: true,
  canPromoteMembers: false,
  canChangeInfo: false,
  canInviteUsers: true,
  canPostMessages: false,
  canManageForum: true,
  canPinMessages: false,
);

sendMessage(
  "Link your chat or channel",
  replyMarkup: ReplyKeyboardMarkup(
    keyboard: [
      [
        // Works
        KeyboardButton(
          text: "📢 Link channel",
          requestChat: KeyboardButtonRequestChat(
            requestId: requestId,
            chatIsChannel: true,
            chatIsCreated: true,
            userAdministratorRights: _kBotAdminRights,
            botAdministratorRights: _kBotAdminRights,
          ),
        ),
      ],
      [
        // Doesn't work
        KeyboardButton(
          text: "👥 Link chat",
          requestChat: KeyboardButtonRequestChat(
            requestId: requestId + 10000,
            chatIsChannel: false,
            chatIsCreated: true,
            userAdministratorRights: _kBotAdminRights,
            botAdministratorRights: _kBotAdminRights,
          ),
        )
      ]
    ],
  ),
);

In TL terms: keyboardButtonRequestPeer with requestPeerTypeChat

Expected behaviour

Telegram Desktop creates a supergroup, adds the bot there and promotes it to admin with requested rights, triggers SharedChat event

Actual behaviour

Telegram Desktop creates a regular group and fails to promote the bot there, the modal window closes. SharedChat event isn't issued to the bot.

The same markup works successfully on Android and iOS apps. Android and iOS clients create supergroups in the given flow.

Operating system
