Emergency Brakes signer rotation

It is proposed to rotate one of the Emergency Brakes multisigs signers.

The 3/5 Emergency Brakes multisigs have been introduced to safeguard Easy Track and L2 bridges (specifically Arbitrum and Optimism). Please, follow this link for more details on multisig composition. Emergency Brakes multisigs can:

• pause the Easy Track
• pause wstETH bridges to Arbitrum/Optimism on mainnet and L2 side

Once paused, normal operations can only be resumed via Aragon voting. Emergency Brakes multisigs do not have the power to transfer any funds.

@vsh will depart the multisig leaving a vacancy, so it is proposed to rotate their address 0x2a96805188e583dd760785A0dE93128504DDd5c7 for @theDZhon (Lido on Ethereum protocol team) with address 0x59f8d74fe49d5ebeac069e3baf07eb4b614bd5a7.

The multisigs affected include:

• Ethereum: 0x73b047fe6337183A454c5217241D780a932777bD
• Optimism: 0x4Cf8fE0A4c2539F7EFDD2047d8A5D46F14613088
• Arbitrum: 0xfDCf209A213a0b3C403d543F87E74FCbcA11de34
