Update the open-source google-java-format plugin for 2020.1.

I couldn't find any good way to make this backwards compatible. Oh well.

FYI, It looks like in 2020.1, we can probably actually use the
ExternalFormatProcessor extension point instead of doing all this hacky
nonsense... they added a #format(PsiFile, TextRange) method you can override.
But I'll leave that for later because 2020.1 is out now and people are mad.
