How I did it

Added sepolia to the list of values for arbitrum in /ape-etherscan/utils.py.

How to verify it

from ape import accounts, project, networks

def main():
    with networks.arbitrum.sepolia.use_provider("<MY-PROVIDER>"):
        account = accounts.load("<ALIAS>")
        account.deploy(project.MyContract, publish=True)
