Update Gson to accept wider version

[jonahgraham]

Yesterday a new version of gson was released. If possible we should widen our version range to accept this new version. Need to run japicmp to make sure that there are no API changes that affect us.

If it is just a version change we'll release a 0.23.1 version of LSP4J so consumers don't need to take any additional action/rebuild and SimRel will end up with the right value.

There aren't any API breaking changes according to japicmp tool:
