Uniswap v3 staker

[bhavik-m]

we need to update few things in docs:

• Connector name UNISWAP-V3-STAKE-A should be UNISWAP-V3-STAKER-B now.
• Staker Connector is now deployed on arbitrum and optimism as well. need to add that too in docs.
• the parameter of these function has been changed

 spells.add({
  connector: "UNISWAP-V3-STAKE-A",
  method: "createIncentive",
  args: [_rewardToken, _length, _refundee, _poolAddr, _reward]
})

we can see what specific changes we need to do here
