[BIP-787] Grant Maxis Amplification Parameter Change Permissions for StableSurge Pools

PR with Payload

Summary & Motivation

In order for StableSurge to continue to gain adoption, the flexibility for the amplification factor to be changed allows for more or less slippage between the pairs in the pool. Due to the nature of stable surge, the end goal is to allow for more efficient swaps and charge higher fees when volatility occurs. The permission to manage this parameter will give the hook maximum opportunity for success.

Reference the deployments repository to confirm the corresponding action-ids. For example Base can be seen here.

Technical Specification:

The DAO Multisig on each network, Ethereum, Gnosis, Base, and Arbitrum will write the respective Authorizer calling grantRoles with the respective roles for startAmplificationParameterUpdate and stopAmplificationParameterUpdate for StableSurge factory created pools, the role will be granted to 0x9ff471F9f98F42E5151C7855fD1b5aa906b1AF7e on all networks… This will correspond to the following table.
