[bridge] provide raw metadata for BridgeCommitteeRegistration commands (

MystenLabs#17782)

## Description 

When validators register their info, most likely they don't have
BridgeNodeConfig yet. In this PR we provide the authority key path
directly to avoid depending on the config.

## Test plan 

How did you test the new or updated feature?

---

## Release notes

Check each box that your changes affect. If none of the boxes relate to
your changes, release notes aren't required.

For each box you select, include information after the relevant heading
that describes the impact of your changes that a user might notice and
any actions they must take to implement updates.
