Bump jsonrpc version

[NikVolf]

should address #5470

Calling this an insubstantial isn't really accurate. Obviously the change here corresponds to some changes in code, but the linked issue also doesn't give any indication of what changed. I think it would be better to give a description of changes made and a link to code for this kind of PR in the future, since as-is it's pretty clear that nobody reviewed it but it's now in master.

Well it was reviewed in jsonrpc crate
Here the diff shows nothing, so there is nothing to discuss and comment really

[rphmeier]

Right, my point is that the corresponding PR should be linked to when we do bumps like this since there's usually more eyes on the PRs here.
