upgrade json-smart

fixes #2435

I'm fine with merging this, but correct me if I'm wrong, this is working around the issue rather than fixing?

I think we should leave #2435 open and (ideally) try to fix before we release on Quarkus 2.0.0.Final. It may not be all that difficult to do, references to json-smart seem quite limited:

So we may be able to add substitutions for that stuff. I could try to look at it some time this / next week.

@jamesnetherton okey then. I'll continue on the work I've started last week to remove it completely
