potential failure of activation when JDK <11 is also installed

[Eskibear]

Context

It simply finds the first available JDK in below order:

• java.home
• JDK_HOME
• JAVA_HOME
• fallback to call node-find-java-home

Steps

Now since it requires JDK 11+, a broken case is:

• both JDK 8 and JDK 11 installed
• java.home not set (for most new users)
• JAVA_HOME points to JDK 8

It will pick JDK 8, and request users to install JDK 11+.

Possible solution

Add new options to find-java-home, like minVersion (requires the library to check version), or request the library to return all possible java homes.

[Eskibear]

ultimately it would be perfect to provide new APIs in upstream, tracked in jsdevel/node-find-java-home#28

A good finding, looks like this is not a rare case.
