Document: CORDOVA_JAVA_HOME environment variable

[breautek]

As pointed out by apache/cordova-android#1229 (comment)

The CORDOVA_JAVA_HOME is not documented as an option. CORDOVA_JAVA_HOME will take precedence over JAVA_HOME if set.

The feature was added in v10 of cordova-android.

PR #1293 is OK,

The JAVA_HOME environment variable must be set according to your JDK installation path when installing on a Windows environment.

This is other issue however, as for sure JAVA_HOME works not only on Windows, but macOS as well.

I bet specific OS should be omitted.

For sure... I didn't change what was already, there I just appended. However this is definitely true and I think this is a good opportunity to address that. Thank you for pointing that out.

It is live at https://cordova.apache.org/docs/en/11.x/guide/platforms/android/index.html#java-development-kit-jdk

And it feels like it should be moved to section https://cordova.apache.org/docs/en/11.x/guide/platforms/android/index.html#setting-environment-variables

I would... also agree with that. A PR is welcome to move it.
