Migrate to https://github.com/gomodules/jsonpatch

It's better we're on the same project that controller-runtime uses so we
can take advantage of any upstream security and bugfixes that may occur
- or have occurred already!

Work on googleforgames#3636 - since if that issue gets fixed, it will get fixed here.

Also, it ws a fun little fix to work on 😃
