Update tooling-setup.md to include Holesky oracle allowlist

Aragon is often running into rpc issues, so i've added the option to do a direct getMembers() call on etherscan to each chain as well. We've been getting q's from operators about this.

+### Oracle Allowlist
+The oracle members are retrievable from the HashConsensus (for the Validator Exit Bus Oracle ) contract on-chain, using the Aragon App or directly from the contract using etherscan.

 ## Example Infra Setup
 
 Lido DevOps team prepared an easy way to get the recommended tooling and its dependencies up and running using [Ansible](https://github.com/ansible/ansible). This is a great way to get familiar with the new tooling. This is an example implementation, and still requires security and hardening by the NO; it can be found on [GitHub](https://github.com/lidofinance/node-operators-setup).
