Create guide for deploying Astria full node

Use https://github.com/celestiaorg/networks/blob/master/celestia-bridge-node.md#run-a-celestia-bridge-node as a starting point

Start by reviewing the linked Celestia bridge-node guide and comparing its deployment steps with Astria's full-node requirements. The work is done when Astria has a standalone guide that explains how to deploy a full node from start to finish, including the necessary configuration and verification steps.
