docs: add Lido Automation Owner multisig

[tamtamchik]

Please, go through these steps before you request a review:

📝 Describe your changes

1. Add section 2.21 Lido Automation Owner Multisig to docs/multisigs/committees.md: address, purpose, 3/5 quorum and the list of signers.
2. The multisig is technical and does not manage or custody any funds, so there is no forum post or Snapshot vote behind it.

🔎 Attach a source of truth or evidence that allows reviewers to confirm the changes independently

1. Safe setup (owners and 3/5 threshold): https://app.safe.global/settings/setup?safe=eth:0x23AC4BF8ca7345eE533B12705aF40F69060D9b5b
2. Signer verification for the new addresses:
   • folkyatina: https://etherscan.io/verifySig/334857
   • PolyGrimbo: https://etherscan.io/verifySig/334858
   • arwer13: https://etherscan.io/verifySig/334859

LGTM, though only the Ethereum Safe is linked. Section 2.8.2 already shows the format for one address on several networks.

We should have it for: Ethereum, Arbitrum, Base, Optimism and Linea.

Thanks for adding this to the registry!

One thing before approval - the signer verifications don't yet follow the address ownership guide: the signed message should name the handle and the multisig, be posted publicly, and be linked from a forum post. The two out of three new signatures are address-only, and others attest the Safe Harbor Committee multisig, not this one.

I get that the multisig is technical and holds no funds but that explains no Snapshot, but doesn't waive verification IMO. Hence, the verification should keep the name and address bindings independently checkable.
