This diff updating `prod` and `dev` yarn scripts for the keyserver to include the building of the `rust-node-addon`. To build and re-build the `rust-node-addon`, we should run `yarn workspace rust-node-addon build` command.
Adding the building command to the `prod` and `dev` scripts makes sense to use a single command to build all of the sources and dependencies.
