Update SDK after fixed gas price protocol changes

[begonaalvarezd]

A new protocol upgrade introduced a change so that the gas price is fixed and not proposed by validators before the next epoch. This change comes with multiple things we should update in our apps and sdks

• Sync SDK with latest crates: open rpc & graphql

More changes TBD since the APIs might have changed and now the gas price comes from the system status or similar.

Depends on #3517
