Remove support for Libretiny generic-rtl8710bn-2mb-788k

[mathieucarbou]

@kuba2k2: Due to recent changes in AsyncTCP from @willmmiles PR #58, libretiny board generic-rtl8710bn-2mb-788k does not compile anymore.

See: https://github.com/ESP32Async/AsyncTCP/actions/runs/15374545657/job/43257818677

I am disabling it.

The PR #58 uses direct to task notifications instead of a queue. It seems that FreeRTOS v8.2.0 was the first to support task notifications, and LibreTiny's port for RTL8710BN uses FreeRTOS v8.1.2.

I'll try to update Realtek's FreeRTOS to v9.0.0 or newer. I'll report back once I do, today; however if releasing the new version is urgent for you, then the support can be restored in a future version.

Thanks,
There is no urgency for now: Libretiny is the only PR merged right now requiring a new release for it to be included in ESPAsyncWebServer.
