Prettier Java

This is a personal fork of Prettier Java
that undoes this bizarre formatting choice:

``java
public class Foo {
public static void main(String[] args) {}
}

// becomes

public class Foo {

public static void main(String[] args) {}
}
``

i.e., classes have an extra unbalanced blank line for no good reason.

For any other info check out the original repo. The only material change I made
is not emitting that blank line. The project also uses modern Yarn (v4) now.
