fix: Update isSupported check for sendData method

[makisukurisu]

Fixes #673

⚠️ Not tested ⚠️

Working under the following assumptions:

• tgWebAppData is equivalent of WebAppInitData;
• tgWebAppData is set under the same circumstances as WebAppInitData;
• sendData method is available for mini-apps running from inline mode.

If tgWebAppData is not processed as WebAppInitData type object is, I suggest to reject this PR.
If tgWebAppData is processed more or less the same, but sendData is not available for inline mode, additional checks would be required, for example:

    isSupported() {
      // tgWebAppData is set only when the app is launched
      // via a keyboard button OR from inline mode
      const isDataSet = launchParams().tgWebAppData !== undefined;
      const isLaunchedFromInline = launchParams().tgWebAppBotInline;
      // Since `sendData` is not available from inline mode, we need to:
      // 1. Ensure we don't have `tgWebAppData`
      // 2. Ensure the app is not launched from inline mode
      return (!isDataSet && !isLaunchedFromInline)
        ? 'The application must be launched via a keyboard button'
        : undefined;
    },

(If I'm not mistaken in the boolean checks 😅)

From local debugging.

With a setup more or less, like here:

The problem here is that in some cases, launching the application via Inline Keyboard Button, Telegram still sends init data. I have checked Telegram SDK and they don't perform any checks here. I assume, we should do the same - disable any additional checks.
