Small mistake in wiki

Hi,

I think there is a small mistake in this page : https://github.com/excilys/gatling/wiki/Checks#wiki-json

In JSON, the root element has no name. This might be a problem when it’s an array and one want to target its elements. As a workaround, Gatling names it _.

It should be ‘$’ instead of ‘_’.

Thanks!

Actually, this comment has to be removed: it was about the old JsonPath syntax that was dropped a long time ago.
Thanks for reporting!
