fix: add missing consensus constants to get_constants grpc (#5183)

Description
---
Adds `validator_node_registration_min_deposit_amount` `validator_node_registration_min_lock_height` `validator_node_registration_shuffle_interval_epoch` fields to `get_constants` base node GRPC method.

Motivation and Context
---
These fields are required for L2 consensus

How Has This Been Tested?
---
Type changes only, lints pass

<!-- BREAKING CHANGE: Description what the user should do, e.g. delete a database, resync the chain -->
