Update Android Docs

[zugazagoitia]

The SDK versions in the documentation might/should not work with Javalin 5/Jetty 11.
See: javalin/javalin#1821

Will never versions work, or are we out of luck for Jetty 11 ?

[zugazagoitia]

The user who reported the issue got it working with sdk33 (Android 13) I will try to execute javalin testsuite to check if everything works

[zugazagoitia]

First off we should change

2: Target Java 8:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

to Java 11

After some research and several attempts to run Javalin 5 in Android (SDK33 and Android 13, JDK11), I believe it is impossible.

The ServiceLoader class in the android SDK is missing the Provider interface used by Jetty.

I'll update the docs accordingly.
