Issue with CLI when adding multiple addresses to flashborrower list

[LucasWongC]

Hello, I am Lucas from TokenLogic, and I've worked on a PR to update flashborrower list
Here the problem is when I try yarn generate, the CLI allows me to pass only a single address to grant flashborrower role.
So I couldn't write proper configuration. Current implementation is that on AaveV3EthereumLido and AaveV3EthereumEtherFi, it adds a few other addresses in addition to the one mentioned on the config file.

I suggest updating current CLI so that we can pass multiple addresses to grant flashborrower role.
