How to patch the documentation for @JohnzonAny?

[Frank Vanderham]

I'd like to suggest a patch for the documentation found on
https://johnzon.apache.org/index.html for the @JohnzonAny annotation.
What is the best approach for that? I assume that HTML page is driven
from the [johnzon.git] / src / site / markdown / index.md somehow, so
should I suggest a patch to the markdown file?
