[just-toby]

Description

moonpay will no longer support bridged USDC on arbitrum, which means we don't have a reason to keep this token in the codebase anymore

just wanna make sure that whatever token list we use to pull arbitrum token info from is updated with the new Arbitrum native USDC

(wasn't the case with the Optimism/Base token list for Base native USDC, had to make PR on op's tokenlist repo to update)
