Fix for failed teleport in Rococo faucet bot

I couldn't find any release notes regarding this change :(

just went to
https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frococo-rpc.polkadot.io#/extrinsics
and looked up the xcmPallet.limitedTeleportAssets method, where i saw
expected types, which helped to migrate

the only difference is that all networks (westend, polkadot, kusama)
except Rococo use similar types but without "Staging" prefix
Weird, but okay... if/when any other network also starts using Staging -
it'd be easy to fix by adding them to condition.. still wondering how
would I learn about this change in front
