[PATCH pve_flutter_frontend 4/4] chore: use latest ndkVersion from flutter

[Shan Shaji <s.shaji@proxmox.com>]

If ndkVersion is not specified, the following warning will be thrown
while building the app:

> Your project is configured with Android NDK 27.0.12077973, but the
> following plugin(s) depend on a different Android NDK version:
> - jni requires Android NDK 28.2.13676358
> Fix this issue by using the highest Android NDK version (they are
> backward compatible).
>    android {
>        ndkVersion = "28.2.13676358"
>        ...
>    }
