Java: Do not require that FinalizeMethod is protected

[Marcono1234]

The CodeQL class FinalizeMethod currently requires that the method is protected, however subclasses can increase its visibility to public.
https://github.com/Semmle/ql/blob/16f29570291e3560185ae676491a89360cc2933d/java/ql/src/semmle/code/java/Member.qll#L490

Would it be possible to remove that requirement?

Yep. I've put up a PR.
