chore: bump *-serialization

Bumps for the serialization suite that's used for everything from
JSON-RPC through logging to loading configuration files.

Major highlights since the last bump:

* support for compile-time serialization / deserialization
* more strict serialization with requirements for explicit imports to
avoid some json-serialization footguns
* new, much more efficient buffering implementation that among other
things allows for buffer recycling and finally fixes many of the
buffering features
* support for allocation-free buffering of most types, ie when writing
an integer we avoid converting it to a string first (big performance
improvement for json in particular, but also for logging once it gets
bumped)
* fixes for JsonNode interop and large numbers
* beginning of
